[BUG] sipa-fonts causes mixed Thai-ASCII text to be small

[korewaChino]

Describe the bug
When sipa-fonts is installed, Noto Sans Thai will be used as the default Thai typeface but Sarabun will be used for ASCII, which for some reason causes ASCII glyphs to be smaller than Thai glyphs

To Reproduce
Steps to reproduce the behavior:

1. Install sipa-fonts
2. Try to read Thai text in Firefox

Expected behavior
Properly scaled glyphs between ASCII and Thai text

Example: SEC of Thailand's report on CVE-2021–4034 (PwnKit)

Screenshots
Example: An excerpt from the Thai Wikipedia article for Human
