[iOS] Select all with existing range selection replaces range instead of selecting all text

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Daniel Bates]

Following the UIKit fix in <rdar://problem/47333786>, UIKit now asks the WebKit whether it can handle Command + A as "select all" BEFORE it tells WebKit to do it. If WebKit saids it cannot perform the "select all" then UIKit does not tell WebKit to do it and WebKit now thinks it should insert the "a".

Steps to reproduce:

1. Visit <data:text/html,<input type="text" value="Select the last word">>.
2. Select the last word in the text field.
3. Press Command + a.

Then the text field's content is updated to read Select the last a. But no modification should have occurred and the entire contents of the field should have been selected.

This might also mean that the callout bar when there's a ranged selection will now contain "Select All", but I don't think that is necessarily a bad thing :)

It's a nice feature, but it doesn't match platform conventions. So, I'll need to fix up the patch before landing to keep differentiate between when the keyboard is asking and when the callout bar is asking to give different answers.

Looks like I'll need to make a UIKit change to be able to know who called canPerformAction

No UIKit change necessary callout bar calls -canPerformAction with sender UIMenuController.

Do what we do now if -canPerformAction is called by the callout menu code
