Mention List is not next in Tab order when writing an @mention

[markdon]

Describe the bug

In mui-tiptap examples, hitting the Tab key after @ ignores the suggestion list but I would expect it to be next in the tab order. I'm aware that the arrow keys can be used.

This issue may actually be caused by the example implementation and not the mui-tiptap package. I may find a fix and post here.

Expected behavior

The mention suggestion list is next in tab order when it is visible. Perhaps it also traps focus

Screenshots

In TipTap example, hitting the Tab key after @ moves focus through items in the mention suggestion list.
