Centering fletcher diagram in an enum

[rdong8]

I’m having some trouble getting my fletcher diagram to center when it’s inside of an enum:

#import "@preview/fletcher:0.5.8" as fletcher: diagram, node, edge

#let graph = diagram(
  node-shape: circle,
  node-stroke: black,
  $
    W_0 edge(->) &
    W_1 edge(->) &
    W_2 edge(->) &
    W_3
  $
)

// Outside enum works fine
#align(center, graph)

+
  // This doesn't work
  #align(center, graph)

When outside of the enum, the graph appears centered as expected, but when in the enum, the alignment seems to have no effect:

The thing to do is:

- #block(width: 100%, align(center, graph))

The reason is that enum items aren’t naturally full width. You see the same thing with block equations too.

For example:

- This is not full width.
- $ a^2 + b^2 $

This paragraph is longer than the enum items.

I’ve always thought this was strange behaviour of enum and list. Maybe someone else can comment on the reasoning behind it.

There is an open issue #529 about it. From quickly skimming the comments there, it seems like a proper fix is a bit more involved than simply setting the list/enum widths to 100%.
