Description

[The 8472]

Dropping a file from the nemo file manager stopped working. This reproduces on multiple different sites.

Example steps:

1. open https://www.bing.com/
2. click on the image search icon (the camera icon in the search box)
3. drop an image onto the "Drag one or more images here" box -> does not work
4. upload file via the file picker dialog instead -> works

Can you attach D&D log?

Please try to capture broken scenario and attach log from it. Run Firefox on terminal as:

MOZ_LOG="WidgetDrag:5" firefox > log.txt 2>&1

and if you reproduce it attach log.txt here.
Thanks.
