The icons in the page-issues treatment are misaligned after the update to mw-ui-icon.
Developer notes
The use of inline styles in page issues is what causes the problem. The font size of the icon needs to be restricted to the text not the container containing the icon. The line-height for the icon is also different from the text.
At this point a hack hardcoding the top position is probably the best option but should only happen when we've increased the touch area sizes of icons (T230033)
