What is the new behavior?

Location.normalize() strips base href from the provided URL

Does this PR introduce a breaking change?

[ ] Yes
[x] No

[splincode]

I still hope we have unit tests for this.

@arturovt do you think it is possible to test this?

[arturovt]

I really don't mind writing unit tests for that, but this is so unique a case... I find it difficult to answer, also we do a return there if Angular is in test mode as it will break all our tests, just because karma or jest goes to the /context.html URL first

[markwhitfeld]

Ah, that is a good reason to not have tests.
We could work around it by mocking out the location with jest but that may get ugly??

[splincode]

E2E test help you)

[arturovt]

@splincode No. This is very unique case, this was done due to storage + router plugins combination issue.
