A simple mac catalyst app that has a wkwebview for the steps described.

I have a mac catalyst app using a wkwebview. Within that I am using a contentEditable div but the same issue occurs with an input or textarea. Namely when one clicks on said element it will get keyboard focus but does not render a caret until you click it again. Similarly this happens if you programatically focus the wkwebview.

Scenario 1:
* Run app
* Click either the box under the content editable label, textarea label or input label.

Results:
No caret is displayed (or you see a solid non-blinking line). Technically you can type at this point as see that it has focus. If you click it again then you will get the blinking caret.

Scenario 2:
* Run the app
* Click into the content editable box, the textarea box or input box.
* Click it again. (Not required but you’ll see the caret blinking.
* Click in the textfield below the “Click To Focus” label so that the textfield becomes the first responder
* Click/tao the “Click To Focus” label.

Results:
No caret is displayed. Again technically you can type so it has keyboard focus. Note clicking the label again won’t help but if you click in the editable element it will start to show the caret.
