The text font falls back on a different font depending on the fallback font used

How to reproduce:

1. Open the “TMPBugReport.zip“ project
2. Open the “BugRepro“ Scene
3. Observe the second line of text in the Game view (it is a bolded “Inter” font)
4. Find “Assets/Fonts/Latin/Inter/Inter400Regular SDF.asset” in the Project tab and select it
5. In the Inspector, change the fallback Font from “NotoNaskhArabic-Bold SDF“ to “NotoNaskhArabic-Regular SDF“
6. Observe the second line of text in the Game view

Actual result: it becomes a bolded “NotoNaskhArabic-Regular SDF” font
Expected result: It stays the same, bolded “Inter“ font
