Sometimes, hyperlinking text (or a word) that is followed by a comma or parenthesis will "eat" the comma
This started happening with Evolution 3.38.x (I'm running 3.38.3)
Sometimes (quite often actually), when I type something (in the HTML composer) like blah blah banana banana, blah blah
, and then I go back to select "banana banana" (or maybe just the last banana), click the hyperlink button, paste a hyperlink in there and hit Enter to apply, it will create the hyperlink but remove the "," after banana.
It's quite annoying because then you can't just add/type a "," by positioning your cursor at the end of the word because the newly created comma will then be part of the hyperlink, so you have to go to the word after (leaving a space), type ", " (comma with a space), then go back two characters and delete the extra space before the comma.
I haven't yet managed to find exact reproduction instructions because everytime it happens and I try to reproduce it with a new clean/simple email, I'm unable to... but maybe you will be able to trigger it on your side already, so I'm filing this issue now in case somebody else has seen this too.
