Fix Powerpoint say all on new slide

[LeonarddeR]

Link to issue number:

Follow up of #17488

Summary of the issue:

Since #17488, entering a slide show in Power point no longer activates say all when that browse mode option is disabled. However, I intended this to also apply to cases where you'd move from one slide to another, which didn't work.

Description of user facing changes

NO say all when moving from slide to slide in a slide show and the browse mode option is disabled.

Description of development approach

Expanded the reportSlide method.

Testing strategy:

Tested moving from slide to slide with say all on page load enabled and disabled.

Known issues with pull request:

None known.
