File mode specification error after last update

[XO39]

Was working on some angular project when I updated to last version just an hour ago, then when ever I try to open an html file, this annoying error appears:

File mode specification error: (args-out-of-range gray 0 5)
web-mode-fontify-css-rule: Args out of range: "gray", 0, 5

Here is the output of web-mode-debug:

And this is the backtrace log:

Also seeing this same issue, here's my web-mode-debug:

It looks like this began after this pull request got merged in? I'm trying to look at web-mode-fontify-css-rule to see where the out of range error could be originating but I haven't dug into web-mode source before.

What's interesting is, I get different errors in different files, and I can't always see what's triggering it. For example, trying to visit or save this file: https://gist.github.com/bearguns/e3b64ea9b9b07c9f204634dbe3e0f949 results in: Args out of range: "tan", 0, 4.

This file: https://gist.github.com/bearguns/138524f8d27cd63448a6badaf4f84f95 results in: Args out of range: "grey", 0, 5

Interestingly enough, they don't contain references to CSS colors, and the word "tan" is a part of a word, not something that has any chance of getting tokenized as such.

I have the same problem too

should be solved with last commit
