When files have an opaque origin, the "file" scheme is omitted from the
blob URL serialization in the stack trace.
This change normalizes the output in the test so that both tuple
file origins and opaque file origins (which may serialize as
'blob:ladybird/') is accepted, ensuring the test passes in
both scenarios.
Issue #6294 describes an edge case where the browser crash if the same
module is loaded three times in a document, but all attempts fail.
Failure scenario:
1. Module load 1 set the state to "Fetching"
2. Module load 2 registers a callback to `on_complete` since the
current state is "Fetching"
3. Module load 1 finish with a failure, invoking the callback for load
number 2
4. Module load 3 cause a crash. The state is neither "Fetching" or
"ModuleScript", so we'll reset the state to "Fetching". This invokes
the callback for module load 2 again, now with an unexpected state
which will cause an assert violation.
Proposed fix is to remove the condition that invokes `on_complete`
immediately for successfully loaded modules only, the callback should
be invoked regardless of whether the fetch succeeded or failed.
This reveals a separate bug in HTMLScriptElement, where
`mark_as_ready()` can be invoked before
`m_steps_to_run_when_the_result_is_ready` is assigned.
This appears to be a spec bug, reported as
https://github.com/whatwg/html/issues/12073 and addressed by delaying
the callback by a task, similar to the issue was resolved for inline
scripts.
Atlassian login gets the base URL for its module scripts by throwing an
error and pulling out the current script's URL from error.stack with
regex.
Since we only returned a basename for module scripts, it would fail to
match and try and use `/` as a base URL (because it does
[matched_string] + "/"), which is not a valid base URL.
