Comment on attachment 355917 [details] Patch r-, this doesn't fix the issue. Another reproduction case: 1. open WebInspector 2. enable the Audit tab 3. select "Demo Audit" > "Result Data" > "data-domNodes" 4. close WebInspector 5. reopen WebInspector 6. select "Demo Audit" > "Result Levels" > "level-unsupported" => both "data-domNodes" and "level-unsupported" are selected

This also is the case for the Elements tab: 1. open WebInspector 2. go to the Elements tab 3. select the <body> 4. close WebInspector 5. reopen WebInspector 6. expand the <body> by clicking on the disclosure arrow 6. select any <div> that is a child of <body> => both the <div> and <body> are selected

This addresses additional defects in SelectionController and TreeOutline, one of which fixes an issue where traversing the tree using the up/down arrow keys would fail to select the previous/next element when the element was on a different level of the tree.

Comment on attachment 356347 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=356347&action=review >> Source/WebInspectorUI/UserInterface/Views/TreeOutline.js:400 >> this._cachedNumberOfDescendents++; > > Aside: we should assert that `_cachedNumberOfDescendants` is equal to the sum of the length of every value in `_knownTreeElements`, or even just set it to be that value (in the case that `treeElement` has already been remembered in the past : > > console.assert(this._cachedNumberOfDescendents === Object.values(this._knownTreeElements).reduce((accumulator, current) => accumulator + current.length, 0)); I'd like to avoid doing work every time an element is remembered/forgotten. I'll fix the bug where `_cachedNumberOfDescendents` is incremented even if the element had been remembered previously.
