Design updates needed for 5.9

• Add tooltips that show “medium”, “small”, etc. to the font size segmented control.
• Scrolling issues with appearance dropdown (report). (discussion/PR)

Design updates proposed for 5.9

• There are only 5-6 font sizes but the styles sidebar still shows a big dropdown. Make sure Twenty twenty two theme uses the segmented control for font sizes.
  • Any complex CSS values currently force a dropdown
  • Non-integer values are now considered simple values as per #36636
• “Custom” should not be an option in the dropdown given there is a specific button for showing the custom size controls.
  • "Custom" might actually be required
• “Default” should not be an option. Unsetting styles should be done with the reset button.
  • "Default" might actually be required
