Bold format. How replace <strong> tag with <span> wich has inline style 'font-weight: 700;'

[mikeKlech]

I want to replace tag with wich has inline style 'font-weight: 700;'

Is it possible?

My workaround is here, but it does not work on iphone(when use mobile formatting)

class CustomBold extends Inline {
        static blotName = 'bold';
        static tagName = 'SPAN';
        static create(value: string) {
            const node = super.create(value) as HTMLSpanElement;
            node.style.fontWeight = '700';
            return node;
        }
        static formats(domNode: HTMLSpanElement) {
            return domNode.style.fontWeight === '700' ? true : false;
        }
        format(name: string, value: boolean) {
            if (name === 'bold') {
                this.domNode.style.fontWeight = value ? '700' : '400';
            } else {
                super.format(name, value);
            }
        }
        formats() {
            let formats = super.formats();
            formats['bold'] = CustomBold.formats(this.domNode);
            return formats;
        }
}

const { parchment } = Quill.imports
const {
	StyleAttributor,
	Scope
} = parchment

class CustomBoldAttributor extends StyleAttributor{
	constructor(){
	    return super( 'bold' , 'bold' ,{
			scope: Scope.INLINE,
		})
	}

	value( node ){
		return node.style.fontWeight
	}

	add( node , value ){
		node.style.fontWeight = value ? "bold" : ""
		return true
	}

	remove( node ){
		node.style.fontWeight = ""
	}
}

//local registry
const registry = new parchment.Registry
registry.register( new CustomBoldAttributor , true )

//global registry
Quill.register( new CustomBoldAttributor , true )

may work
