Remove <span its:translate=\"yes\"> + </span> in <title>
Should the text on https://gitlab.gnome.org/GNOME/four-in-a-row/-/blob/master/help/C/index.page#L19-20 perhaps be written a different way:
<title><media type="image" src="figures/logo.png" width="22" height="22" its:translate="no">
</media><span its:translate="yes"> Four-in-a-row</span></title>
Seem the software mostly use:
<title><media type="image" src="figures/logo.png" width="22" height="22" its:translate="no">
</media> Four-in-a-row</title>
So in the po file instead of:
<_:media-1/><span its:translate=\"yes\"> Four-in-a-row</span>
It would be:
<_:media-1/> Four-in-a-row
