Slate: [IME] FF/macOS: entering accented letters from the Accent Menu inserts double character

[danburzo]

Do you want to request a feature or report a bug?

There is a __bug__ in Firefox/macOS with entering an accented letter from the Accent Menu (by holding down a key and pressing the keys _1_ to _N_).

What's the current behavior?

At the subsequent key press (e.g. moving the caret with left/right arrow key), the non-accented character appears along with the accented one. See video here

What's the expected behavior?

A single, accented letter is inserted. Safari/Chrome work as expected.

Other RTEs

• _Draft.js_ exhibits the same problem
• _ProseMirror_ and _Quill_ don't seem to have it

I believe this is fixed in the latest version of Slate.

This is still happening for me in "slate": "^0.44.12",
But I'm also able to reproduce this in the current demo editor from https://www.slatejs.org/#/rich-text

Should this be reopened @ianstormtaylor ?

Thanks

This occurs in Chrome as well.

There's a PR for this that's looks ready to be merged: https://github.com/ianstormtaylor/slate/pull/3041

Will probably require a slate upgrade
