Change Details

IE5.5 to IE8 released 03/2009 supported the `filter: progid:DXImageTransform.Microsoft.BasicImage()` syntax. (IE8 and IE9 supported `-ms-filter` which was deprecated in IE9 and is unsupported since IE10 released 09/2012.) See * https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms532847(v=vs.85) * https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/platform-apis/ms532967(v=vs.85) * https://learn.microsoft.com/en-us/previous-versions/ms530752(v=vs.85) * https://stackoverflow.com/a/5705449 `filter` is a valid standard CSS3 property unrelated to IE's obsolete `filter: progid: DXImageTransform.Microsoft.BasicImage()’ syntax. Thus modern browsers throw errors in the console to be avoided by removing this old syntax.
