Ionic Framework Version

v8.x

Current Behavior

When ion-datetime is used in a WebView (Capacitor in our case) with font size scaled up by the OS, it becomes impossible to set any date as the wheel will start rotating on its own until it reaches its start.

Video of this issue in Ionic 8.2.5

Expected Behavior

The wheel should haldle the lack of space more graciously. Of course at some point the screen real estate becomes so small it's impossible for it to work/be displayed correctly, but current behaviour is a regression from Ionic 7.

Video of this not being an issue in Ionic 7(.8.6):

The alignment is a little bit wonky and at one point in the video it got stuck in between two values, but it mostly works fine.

Steps to Reproduce

1. Go to the linked highly rudimentary stackblitz demo
2. Open devtools and change the ion-datetime's font-size from 22px to 27px (usually you can't change this value since it's hidden inside shadow DOM, but Android itself can)
3. Try setting a date

Additional Information

This issue only happens when the font-size is scaled, when ion-datetime simply runs out of space it will overflow, but it will still be possible to select a date, despite it being a highly suboptimal situation.
