System: macOS 12.4
Symptom:
After finishing inputing the math equation, I would need to switch to the Chinese input method to input some Chinese characters. The first letter would always be redundantly kept there.
For example, if I type “de” to input the Chinese character “的”，what is kept is “d的”，where the “d” is redundant.
It seems this bug is introduced with the “rich” math editor. In previous versions where math equations are input through plain “\(\)” and “\[\]”, there was no such problem.
