Sometimes it just copies the line to the clipboard without generating any move of the content (expected behavior). But sometimes just by typing ctrl-C with text selected you will see a jump of the page.
I haven't found the pattern, but it looks like doing this close to the end of long pages makes it easier to reproduce.
Version: unspecified
Severity: normal
Yes, fixed in gerrit 106185 (made avaiable in MW-VE in gerrit change 106731). Marking as such.
I am reopening this bug as I am obscuring such behaviour again in FF 26.0 at this page:
https://cs.wikipedia.org/wiki/Mammillaria_standleyi
Way to reproduce:
*Select an item in the unsorted list
*hit CTRL+C
You will see a jump up and down of the page, which is pretty unconfortable during editing.
OK I tried FF 27 and safe mode and I have discovered that problem comes when there are empty list items in undordered list. E.g. If I have:
*M. auricantha R.T. Craig
*M. auritricha R.T. Craig
*M. canelensis R.T. Craig
*M. hertrichiana R.T. Craig
*M. lindsayi R.T. Craig
And I select whatever string on that page and type CTRL+C it "jumps"
Note: to produce empty li is just place cursor on the end of second item and hit several times enter (in this case 2 times).
Well, the problem also encountered on this page:
https://cs.wikipedia.org/wiki/Seznam_lid%C3%AD%2C_kte%C5%99%C3%AD_byli_zabiti_b%C4%9Bhem_Euromajdanu
E.g. when copy&pasting "." between rows it also jumps. Problem confirmed in:
*FF 27 safe mode
*FF 27.0.1
*FF 27.0.1 logged of
In Google Chrome 33.0.1750.117 m it jumps and paste sometimes and just once. In IE 7 VE doesnt work at all.
Using *any* means of copying text is making the ctrl/cmd key cause a page to jump up, not just ctrl-c/cmd-c, in Firefox. Right-click and select "Copy" and the same thing happens to the ctrl/cmd key. I cannot replicate this in Chrome.
Using Firefox 30:
