What's the current behavior?

Cursor will jump to beginning of the line, after typing a char. Other cases just do not behave normally.

Even for the live demo https://www.slatejs.org/#/rich-text,

I got the same behavior as described.
My firefox version is 69.0 on Win10 17763.78

Does anyone have the same bug?

What's the expected behavior?

I was trying the examples using also Firefox 69.0+build2-0ubuntu0.19.04.1 on Linux and experience the same bug.
