🐞 bug report
Affected Package
@angular/common/http
Is this a regression?
No
Description
It looks like HttpClientJsonpModule deletes the JSONP callback function for a request immediately upon cancellation. If the request was still in progress, an error is logged in the console when it completes because the function doesn't exist.
This issue occurs when the time between requests is usually lower than the time a request takes to complete.
