5 years ago On further examination, this particular problem seems to stem from what I think of as a bug in Template:Infobox_opera
From lines 12-16
| subheaderstyle = font-weight: bold;
{{{Caption|{{{image caption|{{{caption|{{{image_caption|}}}}}}}}}}}}
| image = {{#invoke:InfoboxImage|InfoboxImage|image={{{image|}}}|upright={{{image_upright|1}}}|alt={{{alt|}}}}}What this effectively does is append the caption to the subheaderstyle (I dont know why)
Now in this particular case the caption has a nowrap template around an internal link.
The nowrap template translates (transcludes) to a \<span class="nowrap">\</span> section
So you get a td' element that looks like
<td colspan="2" style="text-align:center;font-weight: bold; Sketch of the composer by <span class="nospan">[[Emil Stumpp]]</nospan>" ...jtidy then tries to clean this up - hence the visual effect.
<td colspan="2" style="text-align:center;font-weight: bold; Sketch of the composer by <span class=">
[[Emil Stumpp]]"> ...The en.wikipedia version produces the following
<td colspan="2" style="text-align:center;font-weight: bold; Sketch of the composer by <span class="nowrap">[[Emil Stumpp]]</span>"> ...It could be argued that it is a jtidy artefact but I think its a enwiki template bug
I was looking at pages with \<score> in them and then I cam across this
In the infobox is
[[Emil Stumpp]]">which should not be there The wikitext is{{nowrap|[[Emil Stumpp]]}}I have looked at some other{{nowrapand not found any others that seem to cause the same effect I suspect yet another edge case
