Beta 1.63 breaks calloop 0.4.4 build

[YaLTeR]

Code

I tried this code: https://github.com/Smithay/calloop/tree/v0.4.4 cargo check

I expected to see this happen: successful build

Instead, this happened: build fails on the new beta (1.63)

error: implementation of `ErasedIdle` is not general enough
  --> src/loop_logic.rs:96:16
   |
96 |         Idle { callback }
   |                ^^^^^^^^ implementation of `ErasedIdle` is not general enough
   |
   = note: `ErasedIdle` would have to be implemented for the type `Option<Box<dyn for<'r> FnMut(&'r mut Data)>>`
   = note: ...but `ErasedIdle` is actually implemented for the type `Option<Box<(dyn FnMut(&'0 mut Data) + 'static)>>`, for some specific lifetime `'0`

ahh, the usual logic bugs. i hope they dont make it into beta or, even worse, stable in future
