Add stopEvent option to NodeView.createPlugin

[cgorrieri]

Hello,

I have been trying to set up a NodeView for iframes so when the node is selected a panel hovers over it with the option to edit the attributes or directly paste a full iframe code. The panel shows but when I click in an input, the event seems to be bubbled up and the element rerenders and I lose the focus.

I tried with the example you provide with the speech, and it happens also when I remove the content from the spec (I also have to remove the contentDOM property in the NodeView plugin config).

Finally, I made it work by copying the node-view.ts from the core, uncommenting the stopEvent function, and changing it to:

stopEvent() {
  return this._selected;
}

This is working in my case but I am wondering if there is a more elegant solution that can be generalized.

I am not that proficient in ProseMIrror yet, I have tried to accomplish that with widget decorations but I couldn't make it work the way I wanted. So if you have suggestions on alternative implementations, please let me know.

Thank you!
