Starting today (12/15/2021), when pasting in a link copied from the address bar into the ProtonMail message editor, the font attributes ride along no matter what I do. Even when pasting as plain text, the attributes are persistent and mess up the following lines of text also. According to the editor, the font size is supposed to be 14 but appears to be about 10 (guessing) in the lines following the pasted address. Considering that this is the Brave browser, there are bound to be others out there with a similar setup (Brave and ProtonMail).
I noticed that a Brave update posted yesterday which might indicate that something was changed in the current update that has an impact on font attributes. Just guessing… help would be appreciated in understanding what’s going on.
