This is a follow-up to Julian's suggestion to simplify the CSS for the URL input from Bug 1617237:

I wonder if it wouldn't be easier to keep the URL in debug-target-title rather than having a separate debug-target-url element and make it look like it's part of debug-target-title.
...
We would have to flex-grow: 1 debug-target-title and probably use a different grid template for it (maybe 20px max-content auto).

Right now we render the target title and URL separately and create separate CSS classes for them, adding more bloat to DebugTargetInfo's stylesheet. To simplify this, we should consider rendering the target title and url using one class.
