User NhacNy2412 in the Vietnamese community reported a bug: "When I press Shift button, the cursor will jump back to a random place in the paragraph. Press once and it jumps back once. The place it jumps back usually is the text/link that I pasted in. When I use the old Vector, this error happens only when I paste something, but now when I use the new Vector, it also happens when I bold or italicize texts".
Please check the video here and help her fix it. Thank you so much.
