Placeholder text slow to re-appear after content has been cleared

[endercrest]

Description
Previously, clearing text would have the placeholder text appear again instantly. However, in 0.94.0 (and possibly 0.93.0) that placeholder takes some time to re-appear.

The placeholder works as expected in 0.92.0.

Recording
A GIF or video showing the issue happening. (If you don't include this, there's a very good chance your issue will be closed, because it's much too hard to figure out exactly what is going wrong, and it makes maintenance much harder.)

Steps

1. Create slate editor with placeholder
2. type text in
3. remove text

This can also be replicated on the official examples: https://www.slatejs.org/examples/richtext

Expectation
I would have expected that the placeholder text to re-appear immediately after the text is cleared.

I'm seeing this as well. Tracked it down to slate-react 0.93.0. Most likely from 5a0d397

Also causes some additional issues with my specific Slate editor inside a webview on native where the delayed placeholder after deletion causes the cursor to disappear then subsequent deletes break the editor. This was not the case before slate-react 0.93.0 when the placeholder rendered immediately.

Yeah, it's explicitly waiting 300 ms to show, which seems like an exceptionally long time for the purpose of allowing selections to settle. I wonder what the case is where that would take more than a couple milliseconds?

@edhager do you have any thoughts on this one? About the placeholder delay

[Arkellys]

I agree with the others, 300ms is way too long. It's visually distracting and It looks like a bug. Is it possible to remove this delay?

+1 this is impacting our app
