Help with HTML attribute syntax highlighting

[panphora]

Hi, I've been running into the strangest bug with the syntax highlighting of HTML attributes...

Expected behavior

HTML attributes (e.g. href, class, type) should be yellow, like in this screenshot:

Actual behavior

HTML attributes are blue (i.e. #9EFFFF), just like the HTML tag names:

Steps to reproduce the problem

After this bug popped up with a version of Sublime with a lot of packages and themes, I decided to start with a fresh install. So, my steps were as follows:

1. Uninstall Sublime Text 3 (and delete the directory ~/Library/Application Support/Sublime Text 3/)
2. Restart my computer
3. Reinstall Sublime Text 3
4. Add the Cobalt 2 Theme through Package Control (it's currently my only package)

These are my only custom settings:

"color_scheme": "Packages/Theme - Cobalt2/cobalt2.tmTheme",
"theme": "Cobalt2.sublime-theme",  

Strategies I've already tried

• I tried modifying the cobalt2.tmTheme file manually, moving the Italic HTML attribute names definition around, removing the definition's font style, and renaming the theme itself.
• I tried uploading the cobalt2.tmTheme file to https://tmtheme-editor.herokuapp.com/ to add an additional definition that just affects HTML attributes (i.e. entity.other.attribute-name.html). Then I used this new theme in place of the official theme. That didn't work at all. However, on the theme editor site, I was able to see what the color scheme was supposed to look like, confirming that it wasn't a general error, but perhaps something wrong with my config or version of Sublime...

Specifications

• Version: Latest version of Cobalt 2 through Package Control
• Platform: MacOS Mojave 10.14.2
• Sublime: Build 3207

Getting this to work would really help me. I'm currently working on a project that requires a lot of custom data- attributes and being able to tell them apart from the rest of the code at a glance would be very nice.

Any help would be greatly appreciated!!

I had to switch to a different theme in order to get HTML attribute highlighting working correctly. Any help on this would be awesome.
