Andre Klapper e38f545743 Remove obsolete IE9 filter CSS syntax
Summary:
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.)

`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.

Test Plan: Read the links above, realize it's been 16 years, and agree with me.
