WebView losing selection on iOS on button tap

Description

When we tap on a button with selected text on a webview, the keyboard closes and the text looses the selection.

It's working perfectly on Android but not on iOS.

This behavior doesn't happen by default on native iOS.

The native implementation is the following:

Steps to Reproduce

1. Create a content page with a webview with a content editable html page and a button
2. Tap on the content editable element
3. Write some text
4. Select the text
5. Tap on the button on the content page

Expected Behavior

The keyboard shouldn't close and the text shouldn't loose it's selection nor should the keyboard close.

Actual Behavior

The text looses selection and the keyboard closes.
