Fix middle-click, CTRL+click, right-click etc. on Typehead search results.

Closes T15149

Try the following actions on various typeheads:

• right-click
• middle-click
• CTRL+click
• normal click

Demonstration video (2M) showing After patch (on localhost) and Before patch (here on we.phorge.it), where I middle-click and normal-click on menu entries:

Notes:

• the middle click now works (opening in new tab)
• the CTRL+click (or "command" key + click) now works (opening in new tab)
• the right click now opens the context menu (previously broken)
• the normal click should just click (as usual)

Try on:

• search results while typing in main search bar
• search results when editing a Task Tags / assigned to, etc.
• try to click on other weird places
• $$$
