<pre>
    Following compile shows
```
cat > a.h <<EOF
int a;
EOF

cat > b.h <<EOF
#include </dev/null>
EOF

cat > c.cc <<EOF
#include "a.h"
#include "b.h"
EOF

clang++ -c c.cc -ftime-trace -ftime-trace-granularity=0
```
trace like https://ui.perfetto.dev/#!/?s=8b13a929fe18f4d4beba326368b3d7d1eb668663d8e60a094940f237a094cf7f
But this shows that `b.h` is under `a.h`.

This might be similar issue with https://github.com/llvm/llvm-project/issues/56554.
