In a normal textarea, if you type "teh", then <space>, the "teh" gets corrected to "the". But if you then press <backspace>, the "the" goes back to "teh", which is the correct behaviour I believe.

So it looks like whatever mechanism we're using to implement this feature does not work on docs. My speculation: we implement this feature by deleting the "the" and inserting the "teh". The deletion part doesn't work for some reason in docs, but insertion part does, so that's why we get "the teh".

Auto correction doesn't support Docs because of Docs issue.
The feature should be disable on Docs web sites.
Previous we have a long discussion with docs team.
However, not any progress now.

What would it take to support auto-correct in Google Docs?
I'm meeting with their team for the whole day tomorrow, could be useful if we have asks.

We discussed with Docs team earlier about the bug, but haven't reached a satisfactory solution yet.
