Rename tab title doesn't work in fullscreen mode (or focus mode)

Windows Terminal version

1.15.2874.0

Windows build number

10.0.19045.0

Other Software

No response

Steps to reproduce

1. Open Terminal
2. Press F11 to go fullscreen
3. Press ctrl+shift+p to open command palette and choose "Rename tab title..."

Note: entering "focus mode" at Step 2, instead of going fullscreen, results in the same incorrect behavior.

Expected Behavior

I'm provided with some text entry field (perhaps similar to the one displayed when I try to "Rename window..." so that I can start typing and change the name of my current tab

Actual Behavior

At first, nothing apparent has happened. My cursor is still flashing on my command line and I can type into the command line as normal. If I press F11 to exit fullscreen mode, I can see that the style of the tab title has changed slightly as if it applied the style of tab rename mode, but never managed to focus the field for typing. Clicking inside the tab title text allows me to type and rename the tab.

While it's true that you can't see the tabs in fullscreen or focus mode, you can still see their tabs when using ctrl+tab to navigate between them, so the problem is less trivial than it might seem.
