Description
In shared projects there are two buttons for editing. The gray one, which works fine and the button in the top right corner of the iframe. If some clicks on this button he isn't able to download the hex file afterwards.
To Reproduce
Steps to reproduce the behavior:
-
Share a project
-
Open a new Browser or clear caches
-
Open the shared project url
-
Click on the "Edit" button inside the iframe
-
Click on "Download"
-
See how nothing downloads
Expected behavior
In step 6 there should be a download.

Research direction
Start by reproducing the issue in a shared project using the iframe's Edit button, then try Download in a clean browser session. Compare this path with the gray Edit button that works; done means a hex file downloads from the top-right Edit flow in shared projects, including MakeCode for microbit and calliope.
