We've found regression in the C language server, after applying a formatting to C++ code, the content in the editor becomes broken.

Reproduction Steps

1. Create workspace from C++ stack with console-cpp-simple project.
2. Enable Clangd language server installer if it need.
3. Open hello.cc file and add next content:

                  int isEven(int x)     {
    return x % 2 ==               0;
                    }

4. Apply Edit -> Format.

Expected result: The content should be

    int isEven(int x) { return x % 2 == 0; }

Actual result: The formatting is not applied correctly.

So, we check all existed selenium tests and checked all usecases according to manual test plan for language servers: https://github.com/eclipse/che/wiki/Test-plan-for-checking-Language-servers.
Other bugs, except described above, are not be found.
The testcase above works properly on the master.
