Chrome 143 will start rolling out today (most users get it next week).
It includes a new set of options for your webperf traces — including saving sources & source maps:
developer.chrome.com/docs/devtool...
This makes it easier for those viewing traces outside of the page load to get more context.

The Popover API puts your UI on a separate top layer so you can stop fighting with focus management. Plus backdrop styling so short it fits here:
