Missing highlight in GDocs for space errors inside multiword parentheses

[snomos]

Run the following text through the grammar checker using the Google Docs plugin:

 – Mun beroštan sakka máŋggabealatvuođas ja das ahte olbmot dohkkehit guhtet guimmiideaset.Politihkkárin lea mis ovddasvástádus fuolahit ahte mis lea buorredáhtolaš servodat gos lea sadji buohkaide, dadjá Sanner.Sámi homofiillaid ja lesbbaid fierpmádat ásahuvvui jagis 2002.

In the resulting list of errors, the errors concerning an extra space inside parentheses does not get highlighted in the text, cf the screenshot:

This seems to happen only with parentheses. Highlighting seems to work properly in all other cases.

Also, this only affects the Google Docs version.

This is still the case, and probably the same issue as #54.

This is still an issue, almost four years after it was documented. @zoomix can you have a look?
