fix(split): manual doautocmd BufWinEnter for splits

[pysan3]

reference: https://github.com/MunifTanjim/nui.nvim/pull/197

The exact same thing (multiple hidden splits point to the same bufnr) can happen to NuiSplit as well.

I get the error message: `Invalid 'group': 'nuihide'` when I try to split:show().

Hope this gets merged as soon as possible :)

Thanks in advance.

Looks like this is breaking multiple tests.

You can run the tests locally using: ./scripts/test.sh

I see those tests failing even without my changes, so I doubt those failures are on me.

Besides, 78 tests for nui.split do pass, which is the only file I changed, and I don't think my change will affect other files.

Hmm, I only get test errors on nvim-nightly, and a nightly that's published at least within a week. Nvim-stable works as well.

Working nvim version.

• nvim-stable (v0.9.5)
• Some random nightly that was released probly like a week ago or so.

  NVIM v0.10.0-dev-2129+gba9f86a9c
  Build type: RelWithDebInfo
  LuaJIT 2.1.1703358377
  Run "nvim -V1 -v" for more info

Not working nvim version.

• Today's nvim-nightly.

Can you reproduce the error with the very latest nvim-nightly @MunifTanjim ?

[pysan3]

Seems like this is the PR that should've made things easier, but now backfiring your carefully crafted test suites. I'm not sure tho.
