Note, this crash signature is tracked in bug 1800306; marking that as a dependency of this bug. Maybe this was just a case where infra just got "lucky" and hit that (low-frequency) preexisting crash.
Looking at the backtrace in comment 0 and in the most recent in-the-wild crash, it looks to me like this might be reentrancy where restyling code calls out to gecko which calls back to restyling code, perhaps?
Looking at the most recent crash report (bp-1280ec23-9dd4-47af-aa26-ec0ff0240620), we have a stack where we're pretty clearly going from some gecko code into some restyling code, which then triggers Gecko to flush a font-list-initialization, which then triggers restyle data to be rebuilt and another mutable-borrow on some restyling code that is already mutably borrowed (presumably at an outer layer):
7 libxul.so core::panicking::panic_display
8 libxul.so atomic_refcell::AtomicRefCell<T>::borrow_mut
8 libxul.so <style::gecko::wrapper::GeckoElement as style::dom::TElement>::mutate_data::{{closure}}
9 libxul.so mozilla::RestyleManager::RebuildAllStyleData(nsChangeHint, mozilla::StyleRestyleHint)
[...]
13 gfxPlatform::ForceGlobalReflow(gfxPlatform::NeedsReframe, gfxPlatform::BroadcastToChildren)
[...]
15 libxul.so gfxPlatformFontList::InitFontList()
[...]
20 libxul.so mozilla::ReflowInput::CalcLineHeight(mozilla::StyleGenericLineHeight<float, mozilla::StyleCSSPixelLength> const&, nsStyleFont const&, nsPresContext*, bool, nsIContent const*, int, float)
[...]
20 libxul.so Gecko_CalcLineHeight
21 libxul.so style::gecko::media_queries::Device::calc_line_height
21 libxul.so style::matching::MatchMethods::finish_restyle
21 libxul.so style::traversal::compute_style
[...]
25 libxul.so Servo_TraverseSubtree
32 libxul.so mozilla::css::SheetLoadData::SheetFinishedParsingAsync()
(note the Servo --> Gecko --> font list flush --> RebuildAllStyleData (servo-adjacent) --> "borrow_mut" --> crash, which looks like some styling reentrancy...)
The backtrace in comment 0 here is a bit harder for me to follow as to where-the-reentrancy-is-happening, since we're not literally in .rs code until the innermost section; but it looks like it might be similarly reentrant? Comment 0 shows us calling from SharedStyleSheetCache::LoadCompleted into mozilla::ServoStyleSet::StyleNewSubtree into mozilla::dom::Document::DoResolveScheduledPresAttrs into Servo_DeclarationBlock_SetLengthValue (I'm skipping some intermediate stacktrace levels); and that superficially looks like maybe a Gecko->Servo->Gecko->Servo pattern, similar to the one in the crash report linked above.
emilio, does this make sense? Could you take a look when you get a chance?

Thanks. Let's leave this bug to focus on comment 0; I spun off bug 1904139 for the crash report/reentrancy issue that I described in comment 1.

(In reply to Emilio Cobos Álvarez (:emilio) from comment #2)
Comment 0 is really a race with a different thread which is doing StyleSheet::HasRules in here. That's bug 1887866, which Sunil is looking into, IIRC.
Given this^, let's just dupe this, actually.
Also, I'll move the ni=emilio to bug 1904139 (I suspect you left the needinfo here open as a todo/reminder to look further into the issue that I've spun off into that bug).
