Notes: I am using Orion 0.99.126.4.1-beta web browser. I launched the Query Editor v2 on Amazon Redshift (AWS). The page loaded but then most of the contents disappeared. I turned on compatibility mode in the browser (disables web extensions, content blockers, uses standard Safari user agent), but the issue persisted. I opened the Web Inspector, then reloaded with the Web Inspector open, and noticed a new div element that disappeared right as I clicked on it. The Web Inspector then crashed and offered to let me report this bug. I *think* the bug I was originally investigating isn't present on the latest WebKit. At the very least I can't reproduce it in Safari or Safari Technology Preview. However, I have no idea what went wrong with the Web Inspector while I was investigating.
