Page jumps when I press Backspace key while typing a comment on Facebook

I had this problem with Facebook, only in Edge and not in Chrome, drove me crazy. I installed the Beta version of Edge and all was fine. Then someone else discovered and posted that it was the "zoom" setting in Edge that was causing the problem. So I reloaded Edge, changed the zoom setting to less than before and all is good in FB now. My previous zoom was 125% and now is set to 100% and OK. Zoom is tab specific, so can be higher on other tabs if necessary.

When typing comments in Facebook using Chrome or Microsoft Edge, if I use the backspace key on my keyboard, the entire window jumps up a page so where I was typing is now just off the top of my screen and I have to scroll up to see what I'm typing and if I have to use my backspace again, it scrolls off the top, again.

Is anyone else's Facebook page jumping like this? It only happens on Facebook too by the way.

Chrome, started a week or so ago, right around same time Win 11 started trying to force itself upon me. :( I declined but it has a lil pop up waiting in the corner.... hmmm..

Is this some virus we all have?

Or is it FB doing something strange?

Or is it Google?

Zooming in and out does nothing, nothing does nothing.

Its driving me mad, Stimpy.

Mine was at 110% and I went to 100% and it stopped jumping.

No because I was using chrome when it started, but now strangely enough it has corrected itself.

Yes -started a few weeks ago, If Im typing a comment and use the backspace or delete key or arrow keys it jumps upwards and I have to scroll back to it

Very, Very annoying.
