[Bug] iPad - Entry: Keyboard.Telephone & Keyboard.Numeric display standard keyboard instead of phone/numeric keyboards

Description

In a Forms Entry box, Keyboard.Telephone & Keyboard.Numeric display standard keyboard instead of phone/numeric keyboards on iPad. I didn't notice this issue on iPhone.

1. Open and build UITest > FormsGallery sample in the reproduction link. (Might also be reproducible generally in an Entry field set to Keyboard.Telephone/.Numeric)
2. Go to "Views for Editing Text > Entry (single line) > Enter phone number"

Expected Behavior

Display a telephone styled keypad (or a numeric keypad when switched to that) on iPad & iPhone

Actual Behavior

Full keyboard is displayed on iPad, telephone styled keypad displayed on iPhone. (I didn't double-check Numeric on iPhone.)

Reproduction Link

https://github.com/King-of-Spades/AppCenter-Test-Samples/releases/tag/2.0-b5 ^ My port of the "Forms Gallery" open-source sample. Other sources of the Forms Gallery I suspect could reproduce the issue since I haven't customized this part of the app.
