Incorrect line numbers reported when errors are emitted about tools-python HOT 1 CLOSED

I've figured out the cause of the bug.

This occurs due to the method t_text_end in lexers\tagvalue.py. The method body is:

def t_text_end(self, t):
        r'</text>\s*'
        t.type = 'TEXT'
        t.value = t.lexer.lexdata[
            t.lexer.text_start:t.lexer.lexpos].strip()
        t.lexer.lineno += t.value.count('\n')
        t.lexer.begin('INITIAL')
        return t

The line t.value.count('\n') doesn't detect newlines because the earlier line is stripped of whitespaces and newlines.
