Ctrl+Backspace teleports text cursor

[nh2]

When pressing Ctrl+Backspace to delete the previous word, Element incorrectl teleports the text cursor to the end of the input box; see video:

element-ctrl-backspace-teleports-cursor.mp4

Browser: Firefox 89 on Linux

Steps to reproduce

Minimal repro:

Input: a, Shift+Enter, b. You obtain in your input line the multiline message:

a
b

Place the text cursor behind a, and press Ctrl+Backspace. (On OSX a different keyboard combo might delete an entire word this way.)

Now instead of just deleting the a and placing the cursor in its stead, it deletes the a and teleports the text cursor away.

Version information

This seems to only happen on Firefox
