            Bug ID: 193616
           Summary: Web Inspector: Make completion popover faster
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P4
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: nvasilyev at apple.com
                CC: inspector-bugzilla-changes at group.apple.com

CompletionSuggestionsView.prototype.hideWhenElementMoves calls getBoundingClientRect() every 0.2 seconds.

getBoundingClientRect isn't terribly expensive:

    console.time("getBoundingClientRect");
    let clientRect = element.getBoundingClientRect();
    console.timeEnd("getBoundingClientRect");

It was between 0.02ms and 0.07ms when adding a new property to <body> on webkit.org.

If it's possible, we should use IntersectionObserver instead.
