Displayed mods are not stable-ordered

[Ecpii]

Describe the bug:
Using Double Time in multi and allowing free mods can give submitted scores incorrect mod orders (Hidden appears before Double Time in the mod display). Haven't tested with other mod combinations, but it seems to be an issue with using free mods in multi.

Screenshots or videos showing encountered issue:

osu!lazer version: 2021.502.0

What's the expected ordering here? The order in which mods appear in the mod overlay?

[Ecpii]

I initially expected the mods to be ordered in the same way that a solo score submission would order them (order of the mod overlay, DTHD), but then I realized that it's inconsistent with the mod order on the website (HDDT) as well as the mod order in stable (which also turns out to be slightly different from the website). I think it would be best to have lazer match the website, since they are very similar in design.

I think this should be the responsibility of the client (in the ModDisplay component) to enforce some kind of stable ordering.
