## Issue
Desktop 7022: i18n: Notification title localization lost
## Approach
The current code breaks up the string into an array of strings, so i18n is somewhat impossible.
Since 99%¹ of dynamic notifications come with a `dynamic` property for all the replaceable values, we can actually reconstruct the string however we want.
¹ <sub>_as far as I can find, only `fiat_tip` does not provide the value via `dynamic`, i.e. hardcoded in the string. Boo._</sub>
### Benefits of this approach:
- able to localize the string again
- able to customize the string (e.g. making claim titles italic, fix typos, use more concise strings, etc.)
### Problems with this approach:
- if the api overloads a particular notification type with several strings, then the approach is broken.
- Ex. For the case of `comment` type, the overload is whether the comment is a normal comment or hyperchat. But I was able to replicate the logic to differentiate them, so all is good.
- For the case of "livestream reminder in 30 minutes", we would have to inspect the string to differentiate against "is live streaming". I think this reminder is not being used, so I didn't do it yet.
- some work is needed to maintain the code when the server side updates something. But we are already manually maintaining the i18n strings anyway, so it shouldn't be too much of a burden.
- With the exception of the overload problem, any new notification type will simply pass through as un-localized, so things should continue to work, i.e. no need to update the front-end immediately 🤞
- When collapsing, scroll back to the first comment instead of hanging in the Recommended section.
- Enhancement for 5380bc04: don't show "Collapse/Expanse" if there's only 1 comment. The comment itself is already collapsed to 3 lines, so it won't take up too much height.
- Fix css: recalling what Dan mentioned: if following BEM right (modifiers shouldn't be used standalone), we wouldn't incorrectly use `@extend` in this case and confuse the reader.
- Enlarged the empty spacing to make it symmetrical with the Recommended section below it.

Apparently, the page bubble cannot be made clickable due to accessibility issues, so the click area is very small.
Changed the css as suggested by the maintainer.
## Cause
It broke because lack of awareness that we can't use our components in preview mode. For some reason, we don't have redux access in SimpleMDE's preview mode.
## Change
- Restore the stub for iframes
- Fix preview for images, and apply the same styling as in posts.
- Non-error = pink background, Error = dark red. The former provides bad contrast for --color-text-subtitle.
- Use opacity instead of a hardcoded color.
- Only add for unauthenticated users for now. We can change that to look at premium later without having to touch `app/view.jsx`.
- Only show the ad after knowing the ad is filled; this prevents the invisible container from blocking stuff while waiting, or even worse, when not filled.
