Actually, this is because the "settings" link isn't properly positioned.

The "settings" link isn't correctly positioned because the "Google Translate" is using a no-break whitespace. So the UILabel is correctly displaying it on one line, the util used to get its position isn't taking it into account and is counting it as displayed on two line, creating a discrepancy.

[iOS] Make LabelLink working with unbreakable spaces

When the LabelLink is displaying a text containing an unbreakable space,
the unbreakable space is preventing two words from being broken at the
end of a line. However, the ManualTextFramer used to get the position of
the link isn't respecting the unbreakable spaces.
So the displayed text isn't breaking the words at the end of the line
but the link is positioned as if the words were broken. So the position
of the link is wrong.
