1468334 - After dragging tab to another window, it no longer displays images

Status: RESOLVED WORKSFORME

(Core :: DOM: Navigation, defect)

Attachment: Browser Console log of the tab move

For the past three weeks or so (sorry that I don't have a more precise date), whenever I drag a tab from one window to another (or to create a new window), that tab will no longer load any images. Reloading the page doesn't help, and even going to another page (or even another site) doesn't change anything -- pages continue to fail to load images.

Interesting point to note: when the moved tab first paints, the images are visible. They vanish a moment later, never to return.

I'm attaching a copy of the browser console log from the time period including the drag of the tab out to create a new window.

I verified this issue on Mac  10.13 with FF 62.0a1 (2018-06-14) (64-bit) and I cannot reproduce it. It is also a good idea to create a video  screen recording. This is reproducible only on Mac? Thanks

Hi,
Marking this as Resolved: Incomplete due to the lack of response from the reporter.
If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.

I don't have anything but a Mac to test this on, but I have recorded a video sequence demonstrating it. It is too large to attach to a bug; is there a recommended place to put it?

Attachment: MP4 video showing this happen

Attached a video showing the problem occurring. On the right is the tab in its original window; watch as it's moved to the window on the left; the tab and its contents move, then all images vanish. Note that the images are there for just a moment before they go away.

From this point onward, no images will draw in the tab until it is closed, even on other domains.

The drag and drop won't be the issue here; something about docshell swapping more likely.

I tried with the MDN page shown in the video and it no longer fails, so closing. I'm using today's Nightly.
