bug(windows): modifier key occasionally is 'stuck on'

### Describe the bug

After #7716 addressed the serialization of modifier keys, there is still seen an occasional case where the modifier key sticks on. A log file has been obtained for further investigation.

### Reproduce the bug

Typed the sentence: `Lonh does does`
Output was: `LOnh DOes DOes`

It is likely that the release of the right shift may have been slight after pressing the `o` on the L. However `Shift` was not pressed again for the rest of the sentence so why the `DO`es
