Mention element doesn't work as expected within custom blocks

[HaGalstyan]

What’s broken?

The trigger character @ is not opening the list of users if there's a space before it, it works only next to the text.. For example:

some text @ // won't work

some text@ // works

What did you expect to happen?

Just when the mention element is implemented, the mention element should always appear in the custom blocks when hitting @, regardless of the side conditions.

Thanks, I'm able to reproduce this on https://playground.blocknotejs.org/custom-schema/alert-block with the regular suggestion menu.

It seems this if statement somehow fails:

BlockNote/packages/core/src/extensions/SuggestionMenu/SuggestionMenu.ts

Line 337 in d93906e

if (from === to) {

We'll dive into this later
