Oh, geez. I think my report of "the bug is gone!" was premature.
Full backup, new Windows 2004 install, and the system is lovely, fast, pleasure.
But --- oh oh. Overlapping images are Baaack.
@Sphinx @freemo , FYI, as I am thinking it might be browser related. And I couldn't try in MS Edge, as the add on is required, a FF native one.
Will report if I get any more findings.
So after you upgrade your windows. the compose post function on Waterfox did not work? 
No, I never had that bug -- I think it's on Chrome, possibly, in your case; you should install and try FF to see.
What I have reported, then see working fine, and now again buggy is that Images in the Feed will appear above the Toot Editor .
And that means I must slide them away, and find some area on the feed with text only posts. So that I can see what I am writing, and create a post properly.
Understood and sorry about that
Btw,I installed Waterfox yesterday I feel like it’s better than Firefox in some way.

It certainly is -- an improved and lighter FF experience. I love it. Glad you are trying it out!
Maybe take a look at some of my FF add-on suggestions? Blog post on it :
