I just tested a selfbuilt with https://git.lede-project.org/?p=source.git;a=commit;h=3bef96ef18a6fb20401313dfa6e88057d56b16ad and can't reproduce this issue anymore.

I would like to suggest to cherry pick this commit for Lede v17.01.0 because it will prevent internet outages for users with unreliable DNS servers like me.

PS: Simon Kelley included the fix in dnsmasq-2.77test2: http://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=68f6312d4bae30b78daafcd6f51dc441b8685b1e

Thanks for your support.
