Problem with LaTeX copy/paste

Hi folks,

First, it's pretty cool that one can insert LaTeX equations and so on into wiki pages, using the Insert > Equation Editor function.

However, copying and pasting doesn't work properly in the WYSIWYG editor.

The problem appears to be that the copy function copies the image, but does not copy the latexexpression attribute (nor the imagesize attribute, for that matter).

This problem isn't noticed until later going to edit the pasted equation. The right-click menu offers Edit Equation, but the equation editor shows no actual LaTeX code.

The copy can be performed in the raw html view, but that's difficult to cope with in a long document.

This behavior noted in FireFox 44 on Windows 7.
