@Endcond not behaving as expected (missing warnings, missing output)

[lcmrvk]

Describe the bug

I'm including both of these issues here because I think they might be related.

1. One is that the missing endcondition warning does is not reported in every case in which I'd
   expected to. It does get reported in some cases however.

See:

• example1
• example2
• example3

2. There was a bug \endcond errors not limited to a single file (Origin: bugzilla #624829) #3857 that was fixed in 1.7.2 where the fix automatically inserted an @endcond so that it does not affect content in files which include the file with the missing @endcond.

See:

• example4

See below examples with their expected and actual behavior.

Expected behavior

example1:

todo:

• remove @endcond in A.h which belongs to #define w

expected:

• missing endcondition warning

result:

• no missing @endcond warning, however @endcond seems to be added automatically to the end of the file because B.h (which includes A.h) is not affected
• output is missing everything from A.h as expected

---

example2:

todo:

• remove @endcond in B.h which belongs to #define k

expected:

• missing endcondition warning

result:

• warning is reported as expeced

• #define l missing from output as expected

  ---

example3:

todo:

• remove @endcond in A.h which belongs to #define y

expected:

• missing endcondition warning

result:

• no missing @endcond warning, however @endcond seems to be added automatically to the end of the file because B.h (which includes A.h) is not affected

• #define x (from A.h) is correctly included in output

  ---

example4:

todo:

• remove @endcond in A.h which belongs to #define z

expected:

• missing endcondition warning

result:

• missing @endcond warning reported
• #define j (from B.h), which should be included in the output is missing
• #define l is included in the output as expected

In the current doxygen version (1.9.7) we get warnings about the missing @endcond for the examples 1, 3 and 4.
The example 2 is and was no problem (as also written in the issue).

We see though that with the example2 1, 3 and 4 we also get an incorrect warning like:

B.h:5: warning: Conditional section with label 'INCLUDE_INTERNAL_CODE' does not have a corresponding \endcond command within this file.

When a warning should be given it should not be B.h but A.h

[albert-github]

Code has been integrated in master on GitHub (please don't close the issue as this will be done at the moment of an official release).

[doxygen]

This issue was previously marked 'fixed but not released',
which means it should be fixed in doxygen version 1.9.8.
Please verify if this is indeed the case. Reopen the
issue if you think it is not fixed and please include any additional information
that you think can be relevant (preferably in the form of a self-contained example).
