you need to consider the complications of such notes ...

- tex needs to take the notes into account when determining a page break
- it does so by the insert mechanism
- when floats can't be placed they also become inserts (top and bottom)
- when there are inserts in inserts th eproblem becomes more complex (so
notes inside floats)
- in traditional tex deeply burried inserts disappearm less so in lmtx

There are things that are hard to get right. This works:

\startpostponing
    \startplacefigure[location=here,title={test \footnote{oeps 1}}]
        \blackrule[width=1tw]
        here
        \footnote{hello 1} and
        \footnote{hello 2} and
        \footnote{hello 3} done
    \stopplacefigure
\stoppostponing

\dorecurse{10}{\samplefile{tufte}\par}

Because here the inserts (notes) will migrate but even then one can get
them out of order (unless we renumber, which then is sensitiev for
oscillation).

I occasionally wonder if top floats could be done more directly but
bottom notes still would have an out-of-sync problem
