Content

Coerce the selection to apply to the text inside the text bounds.

Motivation and context

Fixes a crash seen in the Play Store reports.

Tests

I'm not entirely sure on how to trigger this, to be honest. It happens on the view creation, so those values have to be broken before any user interaction, and that could only happen on state restoration, when coming back from another screen. However, I tried navigating while selecting some text and it worked fine.
