doxygen.css problematic lines example (hsl is used in other places as well)

/* The standard CSS for doxygen 1.15.0*/

/* This causes issues */
dl.warning .tt, dl.attention .tt, dl.important .tt {

Describe the solution you'd like

Doxysphinx runs successfully with Doxygen v1.15.0.

Describe alternatives you've considered

Using Doxygen v1.14.0 works for now.

Additional context

• Doxygen - v1.15.0
• Doxysphinx - v3.3.14
