I am reporting this bug here, on community, because I don’t think it is critical, however it impacts our customer
According to the report, the problem occurs on Chrome versions: 79.0.3945.79, 78.0.3904.108 on Mac OS
I checked that before updating my Chrome and I can confirm strange behavior: after I dropped a .png file, instead of being added to the issue it caused opening the image in full screen.
After I updated my Chrome to the newest version, the problem still is present, nothing happens, no reaction from Jira.
[Update] Created a ticket: https://ecosystem.atlassian.net/browse/ACJIRA-2037
