Project Launcher Back Icon Disappears when 'Use Small Toolbar Icons' is Enabled

With 'Use Small Toolbar Icons' checked in the 'Editor Preferences', the 'Back' button within the 'Project Launcher' disappears.

The expected would for the button to get smaller and not vanish entirely.

1. Open a blank project and go into Editor preferences > Appearance > User Interface > Use Small Tool Bar Icons

2. Window > Project Launcher

3. Create a new profile by using the "+" button

4. Edit the profile.

5. Notice how the back icon at the top disappeared when switching from 'Use Small Toolbar Icons'
