Description

The reason is that I found that the fmt feature of my lsp server cannot be used in IntelliJ, but it still work in vscode.
After investigation, I found that I assigned a u32:Max to formatResponse.textedit.range.line in the format's Response
I implemented the lsp server in rust, and u32 was used as the range type in rust's lsp-type, but the range of this value in lsp should be 0-2^31 -1. I think this is the cause of the problem

But I'm not sure whether vscode has special handling for this situation or just forgot to check

Research direction

Reproduce the formatting response with a u32::Max value in formatResponse.textedit.range.line and compare the behavior described for IntelliJ and VS Code. Review the JSON-RPC and LSP range handling to determine the expected treatment of values outside 0–2^31-1, then add regression coverage for the resolved behavior.
