Steps to replicate the issue (include links if applicable):

go to the Wikipedia app for Android (https://play.google.com/store/apps/details?id=org.wikipedia) on my phone, a Xiaomi Redmi Note 8 Pro.

The dark mode is activated (the problem does not occur in light mode).

I consult an article with text between two <maths> tags.

What happens?:
Non-mathematical text is displayed white on black, but mathematical text is displayed black on black, making it unreadable.

What should have happened instead?:
All text in the article is displayed in white on black.

Software version (skip for WMF-hosted wikis like Wikipedia):
