This seems like a serious problem. When you reply on a page with page notices you don't see the notices. I first noticed this on :en:Wikipedia:Administrators' noticeboard, where they're critically important.
Topic on Talk:Talk pages project/Replying/Flow
We've recently added this in T269033, it will be included in this week's deployment (on Thursday on Wikipedias).
The notices will be only shown in the new topic tool, but not in the reply tool, since it seemed to us that they're usually relevant for new topics but not replies (plus they're often unreasonably huge).
I disagree with this logic. Editnotices are placed when it's important for people editing a page to know something. Hiding them seems inappropriate.
I agree on the importance of edit notices, but we shouldn't show them outright in the reply tool; i.e. I can't imagine how hideous and nearly unusable it would become on pages like w:WP:ANI. However maybe we could instead show a little alert icon ⚠️ or something that when clicked, reveals the edit notice.
Either that, or show them full-size but have a means to dismiss them so I don't have to see it every time I reply. For me, part of the beauty of the reply tool is the minimalist design.
Having some sort of visual "Click here for important information" indicator makes a lot of sense.
Having a stable way to hide notices through CSS (preferably TemplateStyles, i.e. the selectable DOM node should be the descendant of a node with mw-parser-output class) would help edit notice authors to scope edit notices to only one or the other and thus declutter the interface. Of course, this won’t work everywhere right after the deployment, so making the edit notices collapsible still makes sense.
This is what I used to have to click past every time I left a comment at w:en:WT:MED:

I do not miss it seeing it 10+ times a week. Also, the last two bullet points are irrelevant to people using the Reply tool or New Discussion tool.
Looking at pages with the prefix of "Template:Editnotices/Group/Wikipedia talk:" (which includes this one), nearly all of them are blank pages, created to suppress unwanted default edit notices.
Research on other wikis has indicated that most edit notices on talk pages contain only information about how to format/sign a comment. These shouldn't be displayed in the Reply tool.
Page notices are now displayed when creating a new section, but not when replying to an existing section's comment. I think this is a very helpful feature for new editors, and it doesn't interfere with normal discussion.
