Since gnome-shell 3.34 (around 3.34.1 - 3.34.2 update) drag and drop with Chrome doesn't work anymore.

To reproduce:
just open a site that allows uploading a file with drag and drop (for example gmail attachment) and try to drag a file from Nautilus: while dragging over everything seems to work fine, but when you drop it (release the mouse) it fails.
I'm experiencing this issue in Wayland, not tested in X11 and it stared after one of the first maintenance updates to gnome-shell / mutter 3.34.x

Does anyone else is having the same issue? Is there any workaround or patch?
This task depends upon

I made some other test and the issue seems related to Chrome 79 only (firefox works fine)

I'm having the same issue, but with both Firefox (firefox-developer-edition 72.0b11-1) and Chromium (chromium 79.0.3945.88-2). Gnome Shell 3.34.3-1, Mutter 3.34.3-1. It used to work just fine a few months ago.

I found, which looks very similar. Trying to use the logging tweak and minimal test case Martin posted in the thread yields the attached log file (at the end it's getting only plain text data, but I tried to move an image).

Note also that it does seem to work properly in Dolphin (tested in

Running under Wayland too if that makes any difference, haven't tested under X11.

...and it works just fine in X11, for every app.
