Defining key binding to switch ascii_mode only change the input language, don't change the punctuation simultaneously

Under the default.custom.yaml file, I define a key bind: - { when: always, accept: Shift+space, toggle: ascii_mode }. I am happy to change the language with the key binding, while I found that the punctuation didn't change.

Then I define another key binding as - { when: always, accept: Control+period, toggle: ascii_punct }. I first change the punctuation after I change to the Chinese so that I can input the Chinese punctuation correctly. To my surprise, the following ascii_mode change works (means that it also can the punctuation without manual trigger the key binding to change the punctuation) well after once manual punctuation change.

This behavior is quite stranger.

Reproduce the behavior using the default.custom.yaml bindings for ascii_mode and ascii_punct, first checking whether changing ascii_mode is expected to affect punctuation state. Compare the two key-binding sequences and define done as consistent, documented behavior or a confirmed fix for the unexpected punctuation change.
