I tried this feature several times. It works great for short texts, but when writing a long reply parts of the texts sometimes disappear completely or get scrambled. This can he very frustrating. I use the feature in the Hebrew Wikipedia. Thanks and cheers, Ithamar 85.250.228.85 17:33, 18 July 2022 (UTC)

We have this as well.
Are you using the "visual" mode, or the wikitext "source" mode?
I got this today in "source" mode (without special chars installed, vanilla installation, writign in plain English). When I tried to paste the title of a WP article for a wkilink, it pasted the formatted title, complete with font and underline, and then the editing field messily and stopped being editable, with deteriorating function. I tried switching to visual mode and back; I couldn't switch. It also looked as if it had lost some of my text, which I copy-pasted back from the unchanged preview. But then the text shifted and it was pasted in the wrong place... In the end I saved it and edited the comment in a seperate edit.
I have previously had intermittent problems copy-pasting into the reply field from other tabs, including from the HTML and from the URL bar. Since I do this all the time, it's very noticable. I paste selections with middle-mouse-button clicks and CTRL-C CTRL-V, and both would not-work simultaneously.
I also often copy-paste from earlier posts to the talk page. I'd like to convert such pasted text to wikisource without prompting when I'm using the source editor; the delay is long even without the pop-up. The most common think I copy-[aste is a username of someone I"m replying to; I've noticed that I have to include a non-marked-up character before their wikilinked username (i.e. " WhatamIdoing") in order to get the option of pasting the linked name instead of plain text. This one is reliably reproducible.
Does this problem seem to appear after copying and pasting? See phab:T319090 for some links to previous bug reports. Also, do you have the GoogleTrans gadget installed? Do you have this problem in safemode?
Sorry for the slow response, and that apallingly ill-proofread post of mine. It does appear after copying and pasting, it does sound similar to a lot of those bug reports, and if it happens again I'll try to reduce it to something like the solid bug report at phab:T302147. I did nto have GoogleTrans installed; I may have had the "Content Translation" beta feature enabled. I will try it with safemode if I see the problem again.
This happened to me again yesterday. I was copying and pasting names from other websites. The devs said that if I can catch it again, the thing to do is to open the "Web console" and send them the error messages (feel free to e-mail me; sometimes they contain URLs or other information that you'd rather keep private). In Chrome, it looks like you go to View > Developer > JavaScript Console; in Firefox, it's Tools > Browser Tools > Browser Console.
Pbsouthwood, this tip might help you track down that bug, too.
Where do I find "Tools"?
It’s in the menu bar, which I think is always visible on macOS, but usually not on other operating systems. Pressing Alt or F10 should reveal it. (If your Firefox is English, pressing Alt+T directly opens the Tools menu; other languages may have other hotkeys. However, Alt and F10 are as far as I know language-independent.)
Something similar just happened to me: this edit just now. I didn't copy/paste; I just typed in "Yep; that's it!" in source mode and it spat out "p; that's it!e". The preview also had the mangled text, but I only noticed after I pressed Ctrl+Enter.
