>+        [iOS] Callout menu overlaps in-page controls when editing a comment in github.com's issue tracker
>+        https://bugs.webkit.org/show_bug.cgi?id=194873
>+        <rdar://problem/46701974>
>+
>+        Reviewed by Tim Horton.
>+
>+        On the topic of supporting web-based rich text editors on iOS, one problematic area has always been handling
>+        conflicts between platform UI (i.e., the system callout menu) and in-page text editing controls. This issue
>+        comes up in websites that don't use the "hidden contenteditable" approach to rich text editing, but also show
>+        additional controls in a toolbar or contextual menu above the selection. In these cases, what often happens is
>+        that system controls overlap controls in the page.
>+
>+        Luckily, the iOS callout menu (i.e. the private UICalloutBar) is capable of presenting with a list of "evasion
>+        rects" to avoid; if the callout bar would normally intersect with one of these rects, then a different
>+        orientation that does not intersect with one of these rects is chosen instead. Currently, the only rect added
>+        here by UIKit when presenting the callout menu is the bounding rect of the on-screen keyboard, but after
>+        <rdar://problem/48128337>, we now have a generalized mechanism for offering additional evasion rects before
>+        UIKit presents the callout menu.
>+
>+        This patch adopts the mechanism introduced in <rdar://problem/48128337>, and introduces a heuristic for
>+        determining the approximate location of controls in the page which might overlap the callout menu. This
>+        heuristic works by hit-testing for clickable (but non-editable) nodes above the bounds of the selection, which
>+        are additionally not hit-tested by advancing outwards from any of the other edges of the selection bounds.
>+        Additionally, any hit-tested nodes whose bounding rects are very large (relative to the content view size) are
>+        ignored (this deals with scenarios where the body or a large container element has a click handler). We then add
>+        the bounding rects of each of the nodes that fit this criteria to the list of rects for UIKit to avoid when
>+        presenting the system callout menu.
>+
>+        The result is that WebKit will, by default, avoid overlapping anything that looks like controls in the page when
>+        showing a callout menu in editable content. In practice, this fixes overlapping controls on most websites that
>+        roll their own context menu or toolbar in their rich text editor.
