Text is not rendered properly in multiple Editor windows when using the Bitmap Text Rendering Mode

Steps to reproduce:

1. Open any project
2. Open the Preferences window's General tab and change "Editor Default Text Rendering Mode" to "Bitmap"
3. Surface A: Open the Multiplayer Center if it's installed(Window > Multiplayer > Multiplayer Center) and observe the panel labels (e.g. the "Casual co-op" label in the Quickstart section)
4. Surface B: Create and open an Animation Clip, Add and hover over an Animation Event, and observe the tooltip

Actual results: Text is not rendered properly (appears blurry / mushy) - in both the Multiplayer Center panel labels and the Animation Event tooltips.

Expected results: Text is rendered properly (crisp), as in the SDF Text Rendering Mode.
