El onebox en el historial de ediciones ocupa un poco demasiado espacio para mi gusto.

gracias por el reporte @Moin 👍

hacer un diff es difícil 😬 pero esperemos que mejore una vez que esto se integre

> <https://github.com/discourse/discourse/pull/43604>
>
> Previously, \`DiscourseDiff\` wrapped every added text token in \`\<ins\>\`, including… the formatting whitespace between tags. Inside a GitHub onebox, whose body is a CSS grid with \`display: contents\` rows, those extra elements became grid items and displaced the title into the 2.5em icon column, where it wrapped one character per line.
> 
> This change appends whitespace-only text nodes to the preceding tag token so they can never become elements.
> 
> It also fixes three things found alongside it:
> 
> \- closing tags were given a class, emitting \`\</h4 class="diff-ins"\>\`
> \- \`class=\` was matched inside attribute values, so \`\[text\](url "class=foo")\` raised \`NoMethodError\` and returned a 500 from the revisions endpoint
> \- the raw view tinted the whole cell even when only some words changed, hiding the word-level markers underneath, and quote backgrounds hid the highlight on an inserted or removed quote
>
