@run-at document-start does not really run at start

[booruce]

I think this might be related to #184 but it's a closed issue so seeing if there's a fix or alternative.

The issue is document-start appears to run at a readyState of "complete" on every subsequent page load. The only reliable way to have it run during a readyState of "loading" is to use "shift+refresh", for some reason that runs reliably 100% of the time at a "loading" readyState.

The only problem is I can't figure out a way to "shift+refresh" on iOS. Any advice?

Since the extension preparation user script must go through several asynchronous requests and the lack of relevant API support in the upstream, we still have no good way to solve this issue.

There is still an open issue tracking this: #459
