Grammarly autocorrections don't work

[churichard]

Description
Grammarly autocorrections don't seem to work anymore.

From looking at this PR, it seems like they did indeed work in a previous version of Slate. And I seem to recall them working not too long ago as well, so this is likely a regression.

Now when you select a correction, the text is inserted at the cursor position and does not overwrite the misspelled word.

Steps
To reproduce the behavior:

1. Go to https://www.slatejs.org/examples/richtext
2. Install + enable Grammarly on the website
3. Type a misspelled word
4. Hover over the misspelled word and select a correction
5. Observe that the correction is inserted at the cursor and does not overwrite the misspelled word

Expectation
Autocorrections should overwrite the misspelled word.

Environment

• Slate Version: 0.66.6
• Operating System: Windows
• Browser: Chrome

This looks like the same issue as the currently broken application of suggestions from spell checking.
