Describe the bug / provide steps to reproduce it

foo = []
for bar in foo
    pass

foo = []
for bar in foo^
    pass

The overview in the scrollbar shows the errors, even though they do not appear in the editor:

Both language servers correctly report the errors:

VS Code shows the errors correctly with the same language servers. Note how the errors are reported with the location past the end of the line:

@CoderParth I don't have a ~/.local/share/zed/` directory. I'm also using pyright and Ruff as my language servers, not pylsp.

My language servers are correctly configured, as the errors are properly reported. Please see the screenshots I included.

You are seeing different errors because you are using pylsp, and it looks like Pyflakes is reporting the errors at the last character of the line (instead of past the end of the line). The bug here is that Zed is not showing errors in the editor if they occur past the end of the line.

For reference the textDocument/diagnostic response from the LSP RPC logs has the following:

result.items:

[
  { 
    "range": { "start": { "line": 1, "character": 14 }, "end": { "line": 2, "character": 0 } },
    "message": "Expected \":\"",
    "severity": 1,
    "source": "Pyright"
  },
  {
    "range": { "start": { "line": 5, "character": 15 }, "end": { "line": 6, "character": 0 } },
    "message": "Expected expression",
    "severity": 1,
    "source": "Pyright"
  },
  {
    "range": { "start": { "line": 5, "character": 15 }, "end": { "line": 6, "character": 0 } },
    "message": "Expected \":\"",
    "severity": 1,
    "source": "Pyright"
  }
]

Which means the diagnostic underline is basically wrapping the \n newline as that's what's after the last character on a line and before the first one on the next line.
