Broken with middlemouse.contentLoadURL=true

[Yenya]

Hello,

I use Firefox on Linux and in about:config I have middlemouse.contentLoadURL enabled, so that when I have URL selected in a clipboard and click with middle mouse button anywhere in the page except textareas and input boxes, the selected URL gets opened instead of the current page. For textareas and input boxes, the URL text is simply pasted into the input element, as expected.

However, when I click with the middle button inside the simplemde editor, the URL in the selection is opened instead of pasting its content, losing all editing done so far.

Expected behaviour: URL text should be pasted into simplemde-controlled element.

Thanks!
