Issue with Draft Posts on hovering Save Button

Replies: 0

If you want to save a blog post draft and move the mouse over the Save button. (Until the tooltip CTRL + S comes up) and then clicks an error message appears.
It’s only with WordPress 5.4/Gutenberg in combination with Edit Flow.

In addition, following error is generated during hovering.
(in an interval of seconds.)
TypeError: f is zero –> components.min.js:7:82573

The error message is:
DOMException: “Node.removeChild: The node to be removed is not a child of this node” –> react-dom.min.js:103:487

I think the Problem is, that on hover a span tag is getting injected into the dom. But I’m not sure.

Thanks!
