Tab Center 1.36.0 with Vertical Tabs Reloaded 0.8.5-alpha

Screenshots below were with 1.34.0, an .xpi for which I found today in ZFS snapshots of my home directory.

The same problems are found with 1.36.0.

Workarounds

It's not enough to disable Vertical Tabs Reloaded before enabling Tab Center. It's necessary to quit Firefox.
