Bug type: C_Cpp.commentContinuationPatterns

Describe the bug

• OS and Version: Windows 10 (20H2, Build 19042.1526)
• VS Code Version: 1.65.0
• C/C++ Extension Version: v1.8.4

Self introduced comment continuation pattern is recognized. But only for one follow-up line.

E.g.:

    "C_Cpp.commentContinuationPatterns": [
      "/**",
      "/*!",
      "//'"
    ]

Starting with this sequence, it works as expected...:

/*!<enter>
 * 

But continuing with:

/*!<enter>
 * asdf<enter>
 

The asterisk is getting lost.

This behavior does not occur with the standard pattern of '/**'.

Steps to reproduce

1. introduce a custom pattern in settings.json
2. use the multi-line comment as described above

Expected behavior
The asterisk should arise in the second follow-up line, too. Just as the default pattern does.

Code sample and logs

/**
 * \internal
 * <- this example works perfectly
 * 
 */
void bar(void)
{

}

/*!
 * asdf
 <- typing <enter> after the 'asdf' above leaves us out missing the asterisk

void foo(void)
{

}
