Autoprefixer produces values that fail tests

[djbuckley]

The values produced by utils/autoprefixer fail the unit tests as the inline style prefixer has been updated to produce correct values.

After running an npm update and then rerunning the tests, the following output is produced :

 1) ./utils/autoprefixer server side should spread properties for display:flex when userAgent is all:
 
      AssertionError: expected { Object (display) } to deeply equal { Object (display) }
      + expected - actual
 
       {
      -  "display": "-webkit-inline-box; display: -moz-inline-box; display: -ms-inline-flexbox; display: -webkit-inline-flex; display: inline-flex"
      +  "display": "-webkit-box; display: -moz-box; display: -ms-inline-flexbox; display: -webkit-inline-flex; display: inline-flex"
       }
 
      at Function.assert.deepEqual (node_modules\chai\lib\chai\interface\assert.js:216:32)
      at Context. (src/utils/autoprefixer.spec.js:36:14)

 
Line 37 in autoprefixer.spec.js expects :
display: '-webkit-box; display: -moz-box; display: -ms-inline-flexbox; display: -webkit-inline-flex; display: inline-flex', // eslint-disable-line max-len
this won't work due to the following issue : robinweser/inline-style-prefixer#132 (basically the author had it outputting incorrect values, that nobody had noticed, so its now correct).

updating this to
display: '-webkit-inline-box; display: -moz-inline-box; display: -ms-inline-flexbox; display: -webkit-inline-flex; display: inline-flex', // eslint-disable-line max-len
will resolve the failing test

Sounds like we would be better off with yarn. Do you want to submit a PR to upgrade our dependency and fix the failing test? :)
