This has been the case for more than a year and it finally annoyed me enough to report it: In Microsoft Edge Browser, using the predefined heading styles in this site's forum rich text editor results in the entire contents of the post becoming that style. This means you can't highlight some text and make it "Header 1" because the entire post will show as Header 1 style. The other rich text editor styling options seem to work. This bug is present in the latest version of Edge in Windows 10 Fall Creators Update and I've seen it all 2017, but could be older.
