Bucket stylesheet rules

Karl Seguin 94d8f90a96 Bucket stylesheet rules 
In the first iteration of this, we kept an ArrayList of all rules with
visibility properties. Why bother evaluating if a rule's selector matches an
element if that rule doesn't have any meanignful (i.e. visibility) properties?

This commit enhances that approach by bucketing the rules. Given the following
selectors:

.hidden {....}
.footer > .small {...}

We can store the rules based on their right-most selector. So, given an element
we can do:

if (getId(el)) |id| {
   const rules = id_lookup.get(id) orelse continue;
   // check rules
}

if (getClasses(el)) |classes| {
   for (classes) |c| {
     const rules = class_lookup(c) orelse continue;
     // chck rules
   }
}
...

On an amazon product page, the total list of visibility-related rules was ~230.
Now, scanning 230 rules for a match isn't _aweful_, but remember that this has
to be done up the ancestor tree AND, for Amazon, this is called over 20K times.

This change requires that the StyleManager becomes more matching/parsing-aware
but a typical visibility check on that same Amazon product page only has to
check 2 rules (down from 230) and often has to check 0 rules.

Also, we now filter out a few more interactive-related pseudo-elements, e.g.
:hover. These aren't supported by the browser as a whole (i.e. they can _never_
match), so they can be filtered out early, when building the rules lookup.

Karl Seguin 964fa0a8aa Add Request.signal 
Allows aborting a fetch. Improves github integration
 2026-03-19 11:40:16 +08:00
Karl Seguin db01158d2d Improve unhandled rejection 
We now pay attention to the type of event that causes the unhandled exception.
This allows us to trigger the window.rejectionhandled event when that is the
correct type. It also lets us no-op for other event types which should not
trigger rejectionhandled or unhandledrejection.

Fixes stackoverflow in github integration.
