Mouse button thinks it's being held down the whole time a preview is being rendered in Backgrounds: Open dialog.

I'm not sure which component this should be filed under, so I'm just adding it under Background preferences for now. (Not sure if it's a more basic issue with mouse click handling, or with the addition of image previews in the Backgrounds prefs specifically.)
I'm copying the description of this from #8778 so that it doesn't get lost in that ticket.
When you select a large image in the Open dialog, a bug is triggered in which the delay in loading the preview apparently causes the dialog to think that the mouse is being held down the entire time, and so when the preview finishes rendering and the file apparently "finishes" being selected, thinking you've been holding the mouse button down the whole time... so the context menu pops up when you don't want it to.
This bug shows up on a number of my wallpapers; anything over around 4 or 5MB for me. Which is about 9 of the wallpapers in my wallpapers folder. Since this appears to be related to the time it takes to load the preview, this might be much more noticeable on slower systems, being triggered by smaller filesizes.
