Having the toolbar jump as you cursor through the document is not ideal, and having tools that change width makes our responsive calculations harder

There are a few approaches:

1. Try to calculate the maximum width and use this
   • Menus items can change dynamically, and in VE when you enter a table, so this would still result in some resizing
2. Use a maximum width with an ellipsis. This is used by GoogleDocs et al.
   • The downside here is that in some languages (probably German), meaningful information is truncated (e.g. "Unterüberschrift..."), but this is still available when opening the menu.
3. Come up with short-text versions of all these headings that are used when the text would otherwise be truncated (e.g. "Sub head 1"?)
   • Difficult to provide translation guidance for these. How short is short enough?
