Replacing embed isn't removing its content

[makepanic]

Hi, thanks for this great library.

I've found an issue when replacing an inserted inline embed.
Somehow the embed content isn't "replace" from the quill instance. This means while not visible, it still exists in its content.

Steps for Reproduction

1. Visit https://codepen.io/makepanic/pen/pOEZZo?editors=0011
2. Select the embed blot (mention)
3. Type any text

Expected behavior:
Console (quill.getContents()) should not contain any embed blot information as it's not visible anymore.

Actual behavior:
Console (quill.getContents()) contains any embed blot information

Platforms:
Confirmed to happen in latest Firefox and Chrome

Version:
1.3.6

I'm a beginner to quill so I'm not sure if it's misusing the embed api and this is expected behavior.

While working around this issue i found that there's also an empty element in the DOM which maps to the "hidden" embed.

I think this is similar issue #2187

I'm facing a similar issue as it doesn't update the content

However, it works just fine if the user first clicks on the text area then move the cursor left or right and then remove the blot. I even have tried on the above example and it worked

It doesn't happen all the time it only happens 3/5 times

It doesn't happen in the fresh Firefox for me, but still an issue in Chrome. The related bug report in Chrome for this one is https://bugs.chromium.org/p/chromium/issues/detail?id=1063046
