It is unfortunate but it's the correct behavior. This happens because all of the comments are "template-affected" by these templates that generate the collapsed lists:

The easiest way to check this is to open the page using VisualEditor (which you can do even on pages we don't support, by adding ?veaction=edit to the URL): https://ar.wikipedia.org/wiki/ويكيبيديا:الميدان/تقنية?veaction=edit

And that in turn happens because the "start" template contains a <div> tag that is not closed on the "end" template. The two templates are:

• https://ar.wikipedia.org/wiki/قالب:أظهر_أول (this is similar to https://en.wikipedia.org/wiki/Template:Collapse_top)
• https://ar.wikipedia.org/wiki/قالب:أظهر_آخر (this is similar to https://en.wikipedia.org/wiki/Template:Collapse_bottom)

I think this can be fixed by just adding a closing </div> tag to the "end" template, that is, changing https://ar.wikipedia.org/w/index.php?title=قالب:أظهر_آخر&action=edit to:

|}
</div><noinclude>

[[تصنيف:قوالب أرشفة]]

{{توثيق}}
</noinclude>

I don't think this can break anything, but I didn't edit the template yet since I'd prefer somebody familiar with ar.wp's templates to have a look at this and confirm :)

Thanks for your help @matmarex!
