On mobile VE, text inside table header cell is overlapping with the sort icon
Sortable headers aren't shown in Minerva as it overrides 'content' which loads 'mediawiki.page.ready' which loads tablesorter. I assume this is deliberate?
We could mirror this behaviour in VE but currently there is no programmatic way to ask the skin if it supports sortable tables, so it would just be a hack.
I've just fixed the style specificity conflict, so that the right padding for the icons is retained. This means we will see icons in edit mode and not read mode, but as there is a task to fix read mode, I feel this is the better fix.
