Preference not honored at launch: Shrink pinned tabs to display only the site icon

[omegadrh]

What happened?

Steps to reproduce

1. Create one or more pinned tabs
2. In Waterfox settings -> General -> Additional Tab Preferences, deselect the option "Shrink pinned tabs to display only the site icon"; observe the pinned tab[s] have some of the site title visible.
3. Ensure the Settings -> General -> Startup option to 'Open previous windows and tabs' is enabled. (I'm unsure if this is required, but it's part of my config.)
4. Exit Waterfox
5. Start Waterfox

Expected behavior

The pinned tabs should retain the setting/behavior of having site title text visible.

Actual behavior

The pinned tabs do not have site title text visible; they only have the site icon visible.

Workaround

Select and then again deselect the option to "Shrink pinned tabs to display only the site icon" after starting Waterfox.
