Description

Group-tabs toolbar missing when bottom toolbar is disabled

Steps to reproduce

1. clean profile, launch Brave
2. open two sites in separate tabs
3. open Settings > Appearance and set Enable Tab Groups to On
4. toggle Enable bottom toolbar to Off
5. tap on the "three dots" menu on the toolbar and select Group tabs
6. select the two tabs, then tap Group
7. after the tabs are grouped, tap on a tab

Actual result

We're missing the group-tabs control on the bottom

Expected result

With the bottom toolbar disabled, we still should see the group-tab control at the bottom

It should look like the below screenshot, but without the very bottom toolbar (which, when disabled, yields this bug!)
