Incorrect highlighting of comments

[coder3101]

/*
CODE HERE
//*/

The highlighting recognizes that this is a block comment and highlights the whole chunk, that is correct. However, if we add / at the start

//*
CODE HERE
//*/

CODE HERE is still highlighted as comment even thought it should not be as it is only 2 lines comments at the start and at the end
