Flagged by [[ https://pixel.wmcloud.org/reports/mobile/index.html | 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
{F70880742}
{F70880746}
**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
**Software version** (on `Special:Version` page; skip for WMF-hosted wikis like Wikipedia):
