+While crawling [File System Access](https://wicg.github.io/file-system-access/), the following algorithms fire an event, or resolve or reject a Promise, within a step that runs [in parallel](https://html.spec.whatwg.org/multipage/infrastructure.html#in-parallel) without first queuing a task:
+* [ ] The [FileSystemHandle/queryPermission(descriptor)](https://wicg.github.io/file-system-access/#dom-filesystemhandle-querypermission) algorithm resolves/rejects a promise directly in a step that runs in parallel
+* [ ] The [FileSystemHandle/requestPermission(descriptor)](https://wicg.github.io/file-system-access/#dom-filesystemhandle-requestpermission) algorithm resolves/rejects a promise directly in a step that runs in parallel
+* [ ] The [Window/showOpenFilePicker(options)](https://wicg.github.io/file-system-access/#dom-window-showopenfilepicker) algorithm resolves/rejects a promise directly in a step that runs in parallel
+* [ ] The [Window/showSaveFilePicker(options)](https://wicg.github.io/file-system-access/#dom-window-showsavefilepicker) algorithm resolves/rejects a promise directly in a step that runs in parallel
+* [ ] The [Window/showDirectoryPicker(options)](https://wicg.github.io/file-system-access/#dom-window-showdirectorypicker) algorithm resolves/rejects a promise directly in a step that runs in parallel
+* [ ] The [DataTransferItem/getAsFileSystemHandle()](https://wicg.github.io/file-system-access/#dom-datatransferitem-getasfilesystemhandle) algorithm resolves/rejects a promise directly in a step that runs in parallel
+
+See [Dealing with the event loop](https://html.spec.whatwg.org/multipage/webappapis.html#event-loop-for-spec-authors) in the HTML specification for guidance on how to deal with algorithm sections that run *in parallel*.
