toggleScrollView() API does not allow to toggle scroll view if scrollActivationWidth is set

[cderv]

Using default configuration, we inherit Automatic Activation of scroll view on mobile.

reveal.js/js/config.js

Lines 285 to 287 in 669cc25

	// Automatically activate the scroll view when we the viewport falls
	// below the given width.
	scrollActivationWidth: 435,

I was trying in this mode to a menu button (using menu pluggin) and a keyboard shortcut to trigger scroll mode using API Reveal.toggleScrollView()

However, it was not working and I checked that in browser console Reveal.toggleScrollView() does not apply.

I debugged step into the logic, and found that at some point in scrollView activate() Reveal.layout() will be called on the new document DOM

reveal.js/js/controllers/scrollview.js

Line 146 in 669cc25

this.Reveal.layout();

which will check for scrollView responsive

reveal.js/js/reveal.js

Line 1035 in 669cc25

checkResponsiveScrollView();

And it will call scrollView deactivate() as long as the scrollActivationWidth is set

reveal.js/js/reveal.js

Lines 1092 to 1120 in 669cc25

	function checkResponsiveScrollView() {
	// Only proceed if...
	// 1. The DOM is ready
	// 2. Layouts aren't disabled via config
	// 3. We're not currently printing
	// 4. There is a scrollActivationWidth set
	// 5. The deck isn't configured to always use the scroll view
	if(
	dom.wrapper &&
	!config.disableLayout &&
	!printView.isActive() &&
	typeof config.scrollActivationWidth === 'number' &&
	config.view !== 'scroll'
	) {
	const size = getComputedSlideSize();
	if( size.presentationWidth > 0 && size.presentationWidth <= config.scrollActivationWidth ) {
	if( !scrollView.isActive() ) {
	backgrounds.create();
	scrollView.activate()
	};
	}
	else {
	if( scrollView.isActive() ) scrollView.deactivate();
	}
	}
	}

Only when scrollActivationWidth is not a number then Reveal.toggleScrollView() will ignore the responsible and work. (like in https://revealjs.com/demo/ where Reveal.getConfig().scrollActivationWidth is null)

I would have expect Reveal.toggleScrollView() to not be impacted by the presentation size logic as it is an API call explicitly done by user or other tools like I am trying to do.

Hope this is clear enough. please to tell me if an example if needed to illustrate better the usage and problem encountered.

Thanks
