using ingroup and anchor causes tests to disappear

[calumblair]

test_anchor_ingroup_bug.zip
MWE attached.
header file:

/**
* \defgroup group1 Group 1
*/

/** \ingroup group1 
(using addtogroup here fixes the problem)
*/
int f(int);

code file:

/**
\test f() should have behaviour 1
\anchor anchor_1
\test f() should have behaviour 2
*/
int f(int)
{
	return 0;
}

Observed behaviour in the test list:

Member f (int)

    f() should have behaviour 1 

Expected behaviour:

Member f (int)

    f() should have behaviour 1 
    f() should have behaviour 2

I think this is specific to ingroup - If I use addtogroup the bug does not appear.
This is present in 1.8.14 and master.

Correction: If I use addtogroup, weakgroup etc. I see similar behaviour on more complex examples.
