A couple of thoughts:

• The "Paragraph" tool is variable width, and so can be quite long, for example "Sub-heading 1" in Catalan is "Encapçalament de nivell 1", and we can't just truncate because the important information (the heading level) is often at the end.
• It may not be obvious that the menu is horiztonally scrollable, epsecially if it is truncated at the end of an icon (for example in the screenshot in the task).

• For the paragraph options, another possible solution on mobile would be to decide which heading styles are most commonly used and include just them there. Something we could consider and decide.
• The idea is to use a white gradient to show there are more options to scroll. Wdyt?

For the paragraph dropdown width, see T411252 which will make it fixed width.

The problem with icons is that while we could probably come up with something for paragraphs (¶ maybe) and blockquote, they may not be widely recognized without text labels. Using "Hx" for headings would also likely require producing language variant icons. This is why we (and Google Docs) have stuck with text-only for these options.

The idea is to use a white gradient to show there are more options to scroll.

In the example you show it ends up being quite subtle. While we've used the white gradient in a few places we may want something stronger here (e.g. a fixed arrow >)?
