On-demand speech mode - NVDA still talks in PowerPoint when going to next slide

[CyrilleB79]

Steps to reproduce:

• Enable on-demand speech mode
• Open a PowerPoint file
• Press F5 to start the slideshow
• Press space to jump to next slide

Actual behavior:

NVDA reports the slide content

Expected behavior:

NVDA should not speak since the action to open the slideshow (F5) or to go to next slide (space) should be executable without any speech feedback in on-demand speech mode.
