Dependency stops getting locked if switching to Git install

[Gallaecio]

All works as expected when using regular packages:

$ cat requirements.in 
scrapinghub-entrypoint-scrapy
scrapy==2.5.1
$ pip-compile |& grep twisted
    #   twisted
    # via twisted
    # via twisted
    #   twisted
    # via twisted
    # via twisted
    # via twisted
twisted[http2]==22.1.0
    # via twisted
    #   twisted

However, if I install the very same Scrapy version from Git instead of from the Python Package Index, twisted is no longer frozen:

$ cat requirements.in 
scrapinghub-entrypoint-scrapy
git+https://github.com/scrapy/scrapy.git@2.5.1#egg=scrapy
$ pip-compile |& grep twisted

Note: It would not surprise me if this is a known issue, but I have checked for possible existing items, but while there are multiple issues about extras, I could not find any that specifically mention the combination of extras and installation from Git being an issue.

This looks to me to be fixed in PR #1519. Hopefully that (and a handful of other PRs) will soon make it to master.

New resolver from #1539 also fixes this issue.

Closing as fixed by #1519, thanks!
