Overflow value(exceeding uinteger) passed into jsonrpc but still work

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
