"Exactly this text" field appears smaller (in height) than the others
 The space between "Not these words" and "One of these words" is different than the space between the other fields
[x] There are some empty rectangular forms ( placeholders? ) inside "These words", "Not these words", "One of these words" and "Only pages with this template", see T189949. Fixed via https://gerrit.wikimedia.org/r/422412, see T189950.
 Infobox content looks strange, it appears to have different fonts for different parts of the text
[x] The file-size boxes problem is addressed here T189950, and also seems to have a patch up already.
 The word "Search" inside the search button looks blurry. It's probably because the font has too little space between the letters.
Spend an hour to try and see how much of that we can and should fix on our side. If we can do painless workarounds, yay! If this should actually be tackled somewhere else, please create the necessary tickets.
