An example of that is the QuotaExceededError <https://webidl.spec.whatwg.org/#dom-domexception-quota_exceeded_err> exception. We expect developers to be able to deal with different quota levels in different browsers, but the exception they get when they hit the limit is the same everywhere. IMO, it may make sense to define an exception that developers can expect in those cases. (maybe depending on what other browsers are doing in that case) > On Fri, 2 Aug 2024 at 01:17, Mike Taylor <miketa...@chromium.org> wrote: > >> Hi there, >> >> Have we done any sort of web compatibility analysis of what this change >> implies?
