Description

Announcement bar text is being cut off on some display sizes if the announcement is long enough.

View demo on codesandbox. In this example the bug will occur at a screen size of 997px.

Reproducible demo

https://codesandbox.io/s/blissful-currying-nqeocf?file=/docusaurus.config.js&resolutionWidth=997&resolutionHeight=675

Steps to reproduce

1. Add an announcement that is sufficiently long
2. Shrink the window size down and the issue should appear when the announcement occupies more than 1 line.

Expected behavior

The announcement bar should resize to fit the whole message.

Actual behavior

The announcement bar is too small to fit the whole message. It clips the message vertically.

Could be a regression from https://github.com/facebook/docusaurus/pull/5430

Probably not a regression, this is what we had before:

Related to https://github.com/facebook/docusaurus/issues/8370, we should probably fix both issues at once ensuring an announcement bar with dynamic height is possible and does not mess up with the docs layout
