bug(web): autocorrect - typing punctuation in editing is sometimes autocorrected away

From epic/autocorrect (19.0.276-alpha):

1. Type `"hello`
2. Type `"`. Banner shows `hello` highlighted.
3. Type ` ` (spacebar). Keyman deletes the previous `"` character.

Expected:

* Keyman keeps the punctuation that I just typed.

(Low priority secondary - 'h' should really be capital there, but that's a limitation in the Eurolatin capitalization logic)
