Double-width diacritic too high/low

[Logo121]

Not sure for how long this has been a problem for (probably predates the overhaul), but the double-width diacritics (e.g. Double inverted breve above) are too high/low. They seem to be placed outside even box drawing characters.

And strangely, they actually seem to be anchored differently for box drawing characters, as I've found while trying to demonstrate the diacritic position: Doesn't happen to the below diacritics tho.

Possible regression/related issue: #596, #1092

It indeed does predate the overhaul. I procrastinated adding the most recent one for a while because the ties all clip outside the line in notepad and notepad++. I had to make an HTML file to test them in a browser just to be able to see them.

Ties have been this high/low for a pretty while. Trying to implement a "proper" tie mechanism (making them to "react" to the marks below them) is very hard and I do not even know whether this is implementable.

I think it's good enough for now to just make it respond to the first character at least, since that's what most other fonts do (like the two shown above)

The position as it is makes it quite hard to use for IPA imo

bump, this issue is still kinda important

again having it respond to the first character (+ marks if possible) is good enough as a "temporary" fix, the "both characters" behavior can be handled later (marginally related to #1789?)

Maybe remove the ‘stale’ label too?
