When a vertical overflow is triggered in the snippets menu, a vertical
scrollbar is added making the snippets menu slightly smaller. Most
widgets properly adapt their width, however the many2many dropdown
widget does not, causing a horizontal overflow and its associated
scrollbar.
Steps to reproduce the bug :
- Drag and drop the "text-image" snippet in a page.
- Click on the image in this snippet.
- Set the "visibility" option to "Conditionally".
- A horizontal scrollbar appears in the editor panel.
This commit adapts the CSS of the m2m widget to solve the issue.
