Formatting text from iOS native action menu should be properly handled

This issue might be considered more like a feature request than a bug, but even though I'm reporting it. 

Steps to reproduce:

1. Open rich text editor example on iOS
2. Long press and select any text in input field
3. Try to format selected text with italic, bold or underline.

Expected: There might be several expected options depends on the field:

1) Text should be formatted when RTF is supported.

2) Options should not be allowed in the field if they are not supported.

3) Options should appear only in the fields that support this feature.

Actual: Text is not formatted.

Reproducibility:  100% **
