Property interpolation-mode appears to be spelled incorrectly

[ncoden]

I am using gulp-sass-lint v1.3.2 with sass-lint v1.10.2.

For the following code:

  img {
    // Get rid of gap under images by making them display: inline-block; by default
    display: inline-block;
    vertical-align: middle;

    // Grid defaults to get images and embeds to work properly
    max-width: 100%;
    height: auto;
    -ms-interpolation-mode: bicubic;
  }

(from foundation-sites / _global.scss)

The following warning is throw:

163:5   warning  Property `interpolation-mode` appears to be spelled incorrectly  no-misspelled-properties

The sass-lint config is :

...
  no-misspelled-properties:
    - 1
    - extra-properties: []
...

(from .sass-lint.yml)

I expect this warning to not be thrown. -ms-interpolation-mode is an non-standard property for IE<=8 (see https://developer.mozilla.org/fr/docs/Web/CSS/Image-rendering)

Edit: I have the same error for -webkit-overflow-scrolling.
