search in filelist bypasses allowed filetype
When trying to add a file to textmedia which isn't one of the allowed types e.g. JPG JPEG PNG MP4 MP3
you can add a file of type SVG by searching for it in the when selecting a file.
When you jsut navigate to the folder you dont see the svg file which is what it should do.
So in the case of an svg, typo3 detects that it is an image and it allows you to crop the svg which isnt possibly.
