- Issue #2464 - Part 3: ResolveModuleSpecifier for import maps. https://bugzilla.mozilla.org/show_bug.cgi?id=1688879 Acquiring import maps. External import maps aren't supported. (ee5b1688dc)
- Issue #2464 - Part 4: Import map JSON parsing code can be tricked by
overwriting Object.prototype properties. Also fix an erroneous comment.
(1bd54a9109)
- Issue #2464 - Part 5: Update Import-Maps implementation to meet the latest whatwg PR 8075. https://bugzilla.mozilla.org/show_bug.cgi?id=1778289 (a3483e7668)

Should always error bailout for external scripts. Error bailout and warn
when import maps are no longer allowed. (c8c19cf811)
- Issue #2464 - Part 8: Fix a release assert when a dynamic module fails
to load. Reorganize the failure handling in execute() to keep the
failed script alive longer. Please note JS::GetModuleScript() can now
return NULL. (19e8f9ba53)

had some code I was testing with in there that didn't work and caused a
formerly passing test to fail This removes this erroneous change. Also
cleanly handle a failure instead of just asserting in debug mode.
(edb7ea4d5b)
- Issue #2464 - Part 12: Fix a debug assert caused by the preload
canceling in part 10. In debug builds canceling the preload causes an
assert when checking top-level. (bda5e653ca)
No official Pale-Moon changes picked since my last build.
No official Basilisk changes picked since my last build.
My changes picked since my last build:
- js: HACK to remove call to IsAboutToBeFinalizedDuringSweep(), since
gcWeakRefs will be cleared later regardless remaining entries, check

Update Notice:
- You may delete file named icudt*.dat and icu63.dll inside program folder when updating from old releases.
