I have fish_escape_delay_ms set to 10 as a universal variable. However, after upgrading to Fish 2.6.0, it seems that setting isn't honored anymore. echo $fish_escape_delay_ms still gives me 10 but the delay is noticeably longer. If I enter set fish_escape_delay_ms for each new shell instance it works fine.

I'm on ArchLinux (4.11.7) using Fish with Termite.
