Hummingbird 1.4.0 has broken q2w3 fixed widget

Hi,

I just updated Hummingbird to version 1.4.0 on both of my websites, PCsteps.gr and PCsteps.com, and it completely broke Q2W3 Fixed Widget, which I use to make this widget on my sidebar floating.

I have tried everything at the minification page of Hummingbird, to disable minify for all files, to disable combine for all files, to revert all the files to the original position, but nothing works. By disabling Hummingbird altogether, the floating plugin works as it should.

Can you please help?

Thank you

Best regards
