feat(limitTo): ignore limit when undefined - #10510

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

CLAs look good, thanks!

I have left a couple of minor comments inline.

Additionally, I believe a little refactoring is in place: it would be better (i.e. more maintainable/performant) to do the NaN check sooner in the code (and return the input itself), so we can (1) "fail fast" and (2) avoid some of the else blocks further down.

But "functionality-wise" it should be OK.

BTW, the commit message and breaking change notice are slightly inaccurate: It is not only undefined but any invalid value, right ?

@gkalpak thanks for the review

I'm lost with the build result. I get:

No output has been received in the last 10 minutes, this potentially indicates 
a stalled build or something wrong with the build itself.

The build has been terminated

from job 1.

@marcin-wosinek: It is a flake (not related to the build) on SauseLabs only. I restarted the job, but since the tests passed on BrowserStack, it should be OK.

I left two "nit-picky" comments on the tests, but other than that it looks good to me.

_{(There's a typo in the BREAKING CHANGE notice btw: behavoir --> behavio[u]r)}

LGTM
