ChangesList: Remove spaces from <td> in EnhancedChangesListGroup.mustache
The special page RecentChanges can included in wiki content via
{{Special:RecentChanges}}
In this case the generated content is parsed by a wikitext parser. The
wikitext parser converts
<td>
<span>Foo</span>
</td>
to the HTML
<td><p><span>Foo</span></p></td>
But the wikitext
<td><span>Foo</span></td>
is converted to the HTML
<td><span>Foo</span></td>
The module 'jquery.makeCollapsible' supports custom collapsible toggle
buttons but only when they are a direct child of the <td> element. When
the module does not find a custom collapsible toggle button it adds the
default button [Expand].
Because of the additional <p> element when including the recent changes
the module 'jquery.makeCollapsible' adds a default collapsible toggle
button.
This change removes the spaces between <td> and <span> to prevent the
<p> elements when including the recent changes.
