Color markings for .log files, not for .txt files

[vincentkoevoets]

Describe the bug Allright guys, I'm at a loss. I've spend the better part of today trying things, but I'm not getting this done. My problem is that Text opens my .log files correctly, but with colored text and also parts are italic. It recognizes the .log files as plain text correctly, because I have added the log file type as text/plain to mimetypemapping.json. So no rich editing, like it's supposed to do. But it appears to be formatting the text in some way anyway. The .log files are essentially just text files, but with a .log extension. If I change the extension in Nextcloud to .txt, the file loads correctly as plain black text without any formatting. Edit: FYI: the log files in question have nothing to do with Nextcloud or Text, they are just log files for things I'm running on a server.

To Reproduce Steps to reproduce the behavior:

1. Open file with .log extension.
2. See parts of text are colored, and some text in italic and maybe some other formatting.
3. Close file, and change extension to .txt.
4. Open file again, and behold! A plain text file without any formatting.

Expected behavior Any file type that has been added as [text/plain] should be shown just like that: as plain text. (right?)
