Hey @frivoal, I was prototyping a change in Edge that would make us match the spec, but I found out I disagree with the test you wrote; when this issue was resolved I read the following reply to @dbaron's questions and thought that if this was correct I agreed with your proposed spec text, but this does not seem to be properly reflected in the spec.

Here is what the spec currently says:
> The UA determines the cursor to display based on the current context, specifically: auto behaves as text over text, and default otherwise. 

Here is what I think the spec should say:
> The UA determines the cursor to display based on the current context, specifically: auto behaves as text over **selectable** text **and editable regions**, and default otherwise. 

`selectable text` is required to allow text in "user-select:none" (or disabled inputs or even text inside the button tag) not to require a text cursor, while `and editable regions` is required to allow a text cursor in a contentEditable div having no content at all, as well as textarea and input with cursor:auto.

Changing the spec in such a way makes all browser pass the test, but the test stops being exhaustive enough to cover all cases. I wrote a new test covering more cases as part of my change, and it shows that currently only Firefox passes the test (and my prototype in Edge).

```
   <p>The test passes if, when moved over every element inside the blue box, the cursor becomes a text-editing cursor over editable regions or selectable text and remains the platform-dependent default cursor otherwise.</p>
 <div id="test">
