With Chrome and Chromium when last link of the column is clicked in category page it may jump to next column and ignore the click. When browser refreshes/redraws the page the link will jump back to the original column. Problem is not category pages specific and it seems to happen also in other lists where "column-width" is used.

Problem is reported when Chrome or Chromium is used with Mac, Linux or Windows platforms. With Safari and Firefox bug doesn't happen.

How to repeat the bug

1. Go to category page with Chrome: https://en.wikipedia.org/wiki/Category:Turku
2. Re-size browser window so that there is only one column
3. click last link of the column (should be "Turku sub-region" which is last element of the column)
   1. Result should be that clicked link will disappear
   2. and if you click again to the empty space where link was it should return.

Origin of the problem seems to be CSS-rule " ul { margin: 0.3em 0 0 1.6em }" which comes from modules mediawiki.skinning.interface and mediawiki.legacy.shared

Temporary fix in fiwiki diff:

mediawiki:common.css
ul {
	margin-bottom: 0.5em !important;	
}
