Bugzilla

OK, here's the issue I'm seeing, to be a bit clearer:

1. open new profile
2. open `about:telemetry`
3. search for `tabs-newtab-button` - no hits
4. click new tab button
5. go back to about:telemetry and refresh the page

Now you see a keyed scalar for the tabstrip (`browser.ui.interaction.tabs_bar`)  that has incremented to 1.

6. switch to vertical tabs
7. click new tab button again (in vertical tabs toolbar)
8. go back to about:telemetry and refresh the page

Nothing has changed.

9. open browser console

there's an error message:

> browser.ui.interaction.vertical_tabs_container - Unknown scalar. 


I think we should (a) not have the warning and (b) we probably want to make sure that we still track clicks on tabstrip widgets when they happen in the vertical tabs container somehow.
