Lines unaffected from sytax errors get formatted wrong on PowerShell 5

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

1. Open a PowerShell 5 window
2. Type the following code with intentional syntax errors:

$code = @"
@(
  @{
    ""
  }
  ""
)
test /parameter
"@

Invoke-Formatter $code

Expected behavior

Slash should not be seperated from parameter since it isn't affected from the syntax error.

@(
    @{
        ""
    }
    ""
)
test /parameter

Actual behavior

Slash is treated as an operator and is seperated from parameter. This behavior is unique to PowerShell 5 and does not occur in v7.

@(
    @{
        ""
    }
    ""
)
test / parameter

If an unexpected error was thrown then please report the full error details using e.g. $error[0] | Select-Object *

首先使用 Invoke-Formatter 和提供的语法错误代码片段复现 PowerShell 5 的情况，然后跟踪在解析错误后处理未受影响行的 formatter 路径。完成标准是 PowerShell 5 保持斜杠附着在参数上，与预期输出一致，同时不改变现有的 PowerShell 7 行为。
