Actual

The bottom border of the blue page notice is eaten by a negative shift of the "Other languages" navbar

Expected.

Other information

On most translatable pages, the layout is as follows:

• mw-pt-translate-header: "Translate this page" (This is inserted by the extension into the skin, and has by default a grey line under it)
• mw-content-ltr.mw-parser-output:
  • mw-pt-languages: "Other languages" (This is inserted by <languages/> markup, usually as the first thing in the content area.)

For example: https://meta.wikimedia.org/wiki/Movement_Strategy/Initiatives

If the markup were different, it would look like this, showing the grey line under "Translate this page"

This works through the below CSS rule:

.mw-pt-translate-header ~ .mw-parser-output .mw-pt-languages {
  margin-top: -1px;
}

Where this fails is when the <languages /> markup is *not* the first thing on the page. Then it ends up eating something different/unexpected.
