When "Bookmark Toolbar Items" are customized to show directly inside main "Menu Bar" and not on "Bookmarks Toolbar", you cannot click such bookmark and open a page if the menu is *hidden* and temporarily shown with "Alt" key.

Reproducible: Always

Steps to Reproduce:
1. Right click bookmarks bar and select Customize
2. Move "Bookmark Toolbar Items" from "Bookmarks Toolbar" to "Menu Bar"
3. "Done"
4. Ensure that Menu bar is hidden (using options). This will also hide bookmark icons which are now part of main menu bar
5. Press and release the "Alt" key to bring the menu bar (along with bookmark items)
6. Click any bookmark icon
7. Menu bar is hidden but nothing else happens
Actual Results:  
Menu bar is hidden which is OK, but the bookmarked page is NOT opened.

Expected Results:  
I expect a bookmarked page to be opened.
