The classic Safari nonsense bugs. When I see a new sentry issue popping up, I can instantly guess if it's going to be Safari or a real error just by looking at the error text.
It's extremely unhealthy for web standards that every deviation from Chrome's behavior is considered a nonsense bug now.
Using right-click context menus to copy/paste only works in Google Chrome. My understanding is that for security reasons, the browser doesn't allow websites to initiate a clipboard read/write. Google Slides recreates the right-click menu in JS, and so no clipboard events can be made from it. But Google Chrome apparently gives special permissions to Google websites, allowing them to have special enhanced privileges to initiate clipboard events.
I'd say that's definitely something that is an abuse of market share, as Google is using market dominance in the browser space to have a competitive advantage in the unrelated presentation software market.
Don't go down with that ship...
