Description

Flagged by pixel UI regression test. Seems to relate to https://gerrit.wikimedia.org/r/c/mediawiki/extensions/MobileFrontend/+/1214088

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

Visit https://en.wikipedia.beta.wmcloud.org/wiki/Languages_can_be_tested#/languages

What happens?:

Language header is larger than production

What should have happened instead?:

The heading needs the following rule:

font-size: 0.85em;

It was being pulled from resources/mobile.pagesummary.styles/pagesummary.less which is unexpected.

TODO

Restore the font-size
The language overlay should uses its own styles rather than reuse styles from an unrelated component. Change to language-overlay-list-header and scope this appropriately
Re-check pixel visual regression test and ensure that the issues are resolved

In languageOverlay.less, I added a style rule including font-size and color (while languageSearcher.less applies other list header styles). I thought the list header styles would be more appropriate in languageOverlay.less versus pagesummary.less (via changing the selector name from list-header to language-overlay-list-header). Let me know what you think about this patch @Jdlrobson-WMF
