It looks this CL [1] added some scripted_task_queue related files to renderer/core/dom
directory, however, it is unclear to me how these files are related to dom. 

If an idl file, such asscripted_task_queue.idl, includes a link to the standard, it would
be helpful to us to understand.

Please see
https://chromium.googlesource.com/chromium/src/+/master/third_party/blink/renderer/core/dom/README.md
for more info.

If you are not sure whether it is okay or not to put files in core/dom, please
make sure to add an owner (hayato or tkent) listed in core/dom/OWNERS in a review.  We are
happy to help.
