Once an error is detected, it does not disappear once the error is resolved

Describe the bug
Once an error is detected, it does not disappear once the error is resolved

To Reproduce
Example code

module test1;
import std::io;

fn int! example_fn()
{
    // comment out this part to see the error will still remain
    defer (try err) { // error in this part
        io::printf("enterring defer try\n");
        // io::printf("value: %s\n", value);
        io::printf("exiting defer try\n");
    }                                                                                      

    // return io::IoError.FILE_NOT_FOUND?;
    return 2;
}                                                               

fn void! main()
{
    int !res = example_fn()!;
    if(try res) {
        io::printf("res :%d\n", res);
    }
    return;
}

then comment out the defer (try err) but the error highlighting will remain even after commenting out

Expected behavior
Expected the error highlighting to be removed once the, part having the error was commented out
