Have just noticed this on https://open.rocket.chat which is running 0.72.x

In the message box type a line.

Press Shift + Enter a couple of times and then paste a line of text.

Go back up to the top line and either Shift + Enter, or add some text and Shift + Enter.

Cursor drops the the end of the pasted text rather than the following line.

This is a change in behaviour from 0.71.1

Possibly related to the font issue here - I guess something has changed in the message box code.
