Select text is not disabled, touch and select are not usable together

Observation
While using this via Vivaldi on an ipad, I somehow got into select text mode, and the whole screen got selected.

Expectation
If touch is used for navigation, select should be disabled.

This is a problem for a lot of touch based UI, here's an example of the css:

Reproduce the issue in Vivaldi on an iPad, then inspect the touch-navigation styles and event handling associated with text selection. Use the linked CSS example as a reference. Done means touch navigation no longer selects the whole screen while the interaction remains usable.
