Fix bookmark clipping

[cndouglas]

• Submitted a ticket for my issue if one did not already exist.
• Used Github auto-closing keywords in the commit message.
• Added/updated tests for this change (for new code or code which already has tests).
• Ran git rebase -i to squash commits (if needed).

Test Plan:

1. Create a bookmark for any page.
2. Set the title to q y p g j.
3. Make sure the letters are not clipped at the bottom.

Fixes #4614

This looks great when bookmark toolbar icons is turned on but when there is not it throws off the vertical alignment a lot. Could you fix? Thanks!

I decided to reduce the line height of the bookmark button and increase the toolbar height. I hope this is the right approach.
