For Wdspec tests I see a huge blob of data set for the `network.dns.localDomains` preference in Firefox since the last wptsync bug has been landed on inbound:

Before that landing it was only a couple of entries long. 

I wonder if this is expected, and maybe related to the following commit:

Geoffrey, can you please check?

All in all those are 312 values now.

Comment 2

[Sam Sneddon [:gsnedders]]

This got reverted in https://github.com/web-platform-tests/wpt/pull/12462 because it broke Windows; see also https://github.com/web-platform-tests/wpt/pull/12459 and the discussion from https://github.com/web-platform-tests/wpt/pull/10953#issuecomment-412665854.

Comment 3

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Thanks. In that case we will have to wait for the next wptsync.

Comment 4

[Henrik Skupin [:whimboo][⌚️UTC+1]]

This got reverted with the wpt sync as covered on bug 1483105.
