Disable Text marking for non-editable objects

Hi there!

Is there a way to prevent label, caption and heading texts from being marked/selected?
Basically I think this shouldn’t be possible for any non-editable objects.

It’s just because it doesn’t look very good if the user for example “unintentionally” double clicks on e.g. an accordion item and then the header gets marked.

Here’s a little demo snippet:

And here’s a screenshot for clarification:

Thank you - works fine!
