LibGfx+LibWeb: Replace remaining OpenType implementation with Skia This change should move us forward toward emoji support, as we are no longer limited by our own OpenType implementation, which was failing to parse the TrueType Collection format used to store emoji fonts (at least on macOS). 2024-09-04 12:29:01 -03:00			`/*`

LibWeb: Suppress false-positive LSan report during WebWorker teardown Problem: For several weeks now, CI Sanitizer runs have been logging leaked RustCompiledRegex objects in the WebWorker process when a worker is torn down while an off-thread script compile is still in flight. Cause: compile_off_thread() (introduced in 4a7dc45b3f0) parses and compiles a fetched top-level script on a ThreadPool worker. The pool's a process-lifetime singleton whose workers are never joined before exit — and that leads to LSan reporting a false positive during teardown. Fix: Suppress the false positive via __lsan_default_suppressions(). 2026-05-31 12:13:04 -03:00			`return "leak:FcPatternObjectInsertElt\n"`
