Web Inspector: Uncaught Exception: TypeError: null is not an object
(evaluating 'this.target.RuntimeAgent')
https://bugs.webkit.org/show_bug.cgi?id=218258
rdar://70736409
Reviewed by Devin Rousso.
SourceCodeTextEditor.prototype.willDismissPopover always released the
"popover" RuntimeAgent object group on `this.target`, but the object
group is actually created using
`WI.debuggerManager.activeCallFrame.target` when paused (see
_tokenTrackingControllerHighlightedJavaScriptExpression). Editing the
Inspector Bootstrap Script exposed the mismatch: it is a WI.LocalScript
with a null target, so `this.target` was null and dereferencing
`.RuntimeAgent` threw.
Resolve the target in willDismissPopover the same way it is resolved
when the object group is created, and skip releasing it if no target
is available.
