Flame graph: Large number of breadcrumbs expands graph width excessively #6028

Description

@vinhill

I'm on Linux, Firefox 152 Nightly.

On a profile with a large number of breadcrumbs like https://share.firefox.dev/3RKVQPY, the breadcrumbs aren't squished together. Not just the .filterNavigatorBar but the whole #flame-graph-tab becomes scrollable and ends up with an excessive width, in my case 15k px.

This is in contrast to #5724. Perhaps that problem doesn't reproduce anymore and got fixed accidentally, which causes my issue?


As a workaround, one can use a tampermonkey script to inject .filterNavigatorBar { max-width: 100vw; }. But that probably wouldn't be a suitable fix as it causes #5724.
