open editor window (via reply or New Topic)
create several lines of text until it’s longer than the visible window height
scroll back up so the end isn’t visible
click somewhere in the visible text and type “:” to begin the emojii process
select one (either in the immediate list or from the “more …” list)
The screen pops down to the end.
The blinky cursor stays where you were typing. You are just no longer seeing that part of the post anymore.
This problem started recently (like past couple weeks maybe?).
The problem was just confirmed on a completely different OS and browser. (so fairly confident it’s not “just me and my weird computer world”)
I know, I know, the “real” solution is to stop adding emojii’s while editing a post. LOL
