(DevTools :: Inspector, defect)

Description

[Girish Sharma [:Optimizer]]

Attachment: Screenshot displaying the weird behavior

STR :
1) I can reproduce it in more than one site, but for reference go to http://worrydream.com/#!/Tangle
2) Interact with the site a little and then inspect any element.
3) The site seems to reset itself (must be programmed that way) (or inspector causes it)
4) Have the sidebar opened (or even not)
5) Close the inspector by clicking on cross on lower right corner.
6) Change tab/close the current tab
7) Find the side bar still there (if it was visible in step 4)
8) The lower breadcrumbs panel is also there, or if not, reappears on further tab change.
9) The rules and computed sections are empty and when clicked on, produce these errors in error console :

I can also reproduce the same behavior with certain pdf documents when viewed by pdf.js

How do you start the inspector?

Comment 3

[Paul Rouget [:paul]]

For the record, right-clicking on a node that is modified after the resize (something happens on onresize here) throws this error:

Error: TypeError: frameWin is null

Line: 74

Comment 4

Right click on the element (or text/image) and select Inspect Element

In both the mentioned pages, the site was fully loaded and nothing resized.

Do you have the same problem when starting the inspector from the Web Dev menu?

Comment 6

[Girish Sharma [:Optimizer]]

Yes, the problem is due to the sudden disappearance of the selected element. Suppose in an SVG, I right click on a oath that appears only on focus and hover. So as soon as I choose Inspect from context menu, the item disappears (basically gets deleted, invalidated, whatever) So now the inspector breaks. Now if you try to close or switch tab, it acts weirdly and do not gets closed.
It also happens in canvas and other similar situations.

I think this is related to bug 746197.

This problem can't happen anymore (toolbox).
