1450929 - Dom elements missing in inspector

Status: RESOLVED DUPLICATE of bug 1460223

(DevTools :: Inspector, defect)

Attachment: missing elements in inspector.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180329154119

Steps to reproduce:

Firefox Developer Edition 60.0b8 (64-bit) - after latest update.
Page inspection, multiple refresh, some DOM element children are no longer visible in Inspector but rendered on page.  "inspect element" / picker cannot focus on element (since inspector panel does not show element).
I cannot reproduce this in any other browser.  View Source does not highlight any malformed html.
Refresh *sometimes* reveals children.
Resize of window seems to exacerbate problem.
Attached screenshot, same html, left image has children expandable/selectable, right does not.


Actual results:

Dom element children not visible in inspector, inspect element or selector does not expand tree to desired child.


Expected results:

Dom element children should be visible in inspector, inspect element or selector should expand tree to desired child.

I can recreate by inspecting an inner element and refreshing page.  If I then inspect an outer element and refresh page the inner children re-appear in Inspector.  I believe this has something to do with auto-targeting previously inspected item on page refresh.

Hello hanscomka, 

Can you please past the site that you use in the attachment in order to try to reproduce this? Thanks

Hard to investigate without having access to a page where this happens. It would be really helpful if you could provide one.
At first sight, it looks related to bug 1460223 to me (at least the screenshot seems to point in this direction). So I'll close it as a duplicate for now. We can always re-open it later if hanscomka provides a test page that proves this is a separate issue.
