'grid-template-columns' is not supported by Internet Explorer. Add '-ms-grid-columns' to support Internet Explorer 10+.

Environment (please complete the following information):

• OS (e.g., Windows 10): Windows 10
• Extension version (e.g., 1.2.3): v1.4.1

Describe the bug: When using a grid layout with grid-template-columns in a CSS file, the extension suggests to use -ms-grid-columns. When added, the error does not disappear.

Repro steps: Write CSS

  display: -ms-grid;
  display: grid;
  -ms-grid-columns: 1fr 1fr 1fr; 
  grid-template-columns: 1fr 1fr 1fr;
}

Expected behavior: Do not show an error anymore

Not sure of the status of work to fix. Another has indicated that the extension is almost unusable as corrected “errors” regarding CSS generate another error actually regarding the correction (errors that contradict each other in how code is used).

I would suggest that the extension add a setting/option in VS Code also to suppress all errors and warning related to Internet Explorer-compatible CSS styling, since the use of Internet Explorer except perhaps for very strictly controlled intranets is now a security issue.

I assume they picked up the suggested .hintrc to exclude IE earlier in the thread. We’ll be making this better for all users shortly by excluding IE by default in webhint: https://github.com/webhintio/hint/pull/5136

But I think we should still track a (albeit non-trivial) fix to webhint’s handling of “alternate names” as this isn’t the only case where such a setup is used in the MDN data. Whether that is this issue or a separate one I’ll leave up to you.
