iOS WebKit2: selection handles become too large when zooming a page.

• Component: WebKit2
• Status: RESOLVED FIXED

[Enrica Casucci]

This happens only in WebKit2, since the WKContentView is now zoomed and all the selection views are child views of the document view.

Can you just call [self _updateUnscaledView]?

I would not reuse "hitView" but use a different UIView* local variable for clarity.

maybe:
for (UIView *subView ...) {
    if (UIView *hitView...)

> Source/WebKit2/UIProcess/ios/WKContentViewInteraction.mm:1695
>  - (UITextRange *)selectedTextRange

I would store inverseScale in a local variable.

I think this deserve a comment with a little explanation of how the UI works regarding the caret width/height.
