Icons on mw.notification popups are cut off. The "i" should be in a circle. For example on <https://en.wikipedia.beta.wmflabs.org/wiki/Main_Page?useparsoid=1>:
**Steps to replicate the issue** (include links if applicable):
* Visit [[ https://en.wikipedia.beta.wmflabs.org/wiki/Main_Page?useparsoid=1 | this link ]], or [[ https://en.m.wikipedia.org/wiki/Special:UserLogin?centralAuthAutologinTried=1¢ralAuthError=Not+centrally+logged+in | this link ]] logged out/incognito
**What happens?**:
The info icon is cut off because it's too narrow to show the entire mask image. Note that the `mask-size` is 20px and the `width` is 16.55px.

**What should have happened instead?**:
The entire icon should display. The icon span's width and the mask-size should be the same (20px):

**Software version**: Codex 2.2.0
This is happening because the icon is shrinking to accommodate the message text. We need to ensure the icon never shrinks in the flex layout.
