 // temporary workaround until LeakSanitizer supports the V8 heap.
 // Those should only fire in (browser)tests. If you see one of them in Chrome,

 // PLEASE DO NOT ADD SUPPRESSIONS FOR NEW LEAKS.
 // Instead, commits that introduce memory leaks should be reverted. Suppressing
 // the leak is acceptable in some cases when reverting is impossible, i.e. when
 // enabling leak detection for the first time for a test target with
