New catch on fr.wp, with <span data-ve-clipboard-key="0.7541924023058636-0"> added to a table here.
Steps to reproduce:
If [text] contains unformated text, links, bold text, italic text or templates: no problem.
If [text] contains section title, subscript, superscript, underlined text, strikethrough text, center HTML tag: it inserts data-ve-clipboard-key span.
If [text] contains a span tag (with red color CSS style), it inserts data-ve-clipboard-key span and add data-ve-attributes="{"style":"color:red"}" to the pasted span.
Note: [text] should already be saved in the article, not added without saving while VE is opening; in order to test.
Still happening is a different thing: can you confirm what you tried on he.wiki to reproduce?
I went looking on the French Wikipedia. This issue, or something similar, still seems to be occurring, e.g. an edit from a few days ago introduced this attribute. This does seem to a very rare issue, however.
Reproduction note: we only add the data-ve-clipboard-key span in browsers which don't support clipboardData custom data formats. This means Safari, IE (not Edge), or Firefox before version 48-ish (August 2016). It doesn't make a difference which browser you're pasting into, but it has to be copied from one of those.
