The best text editor! Good job! But there is a small problem. enableLineBreaks does not remove lines

[ottmark444]

When enableLineBreaks is true in a text block, it adds a new line when you press enter, and this is correct behavior. But when I try to delete these lines using backspace, they are not deleted, and the cursor simply moves up (without deleting the line)

// Quote block code 

export class Quote {
    constructor({data, api, config, readOnly}) {
        this.data = data
        this.api = api 
        this.config = config
        this.readOnly = readOnly
    }


    static get enableLineBreaks() {
        return true;
    }

    static get isReadOnlySupported() {
        return true;
    }

    static get toolbox() {
        return {
            title: 'Quote',
            icon: '', 
        };
    }


    render() {
        this.wrapper = document.createElement('div')

        this.quote = document.createElement('div')
        
        if (!this.readOnly) {
            this.quote.contentEditable = true
        }

        this.quote.classList.add('quote')
        
        this.quote.placeholder = '...'   

        this.quote.innerHTML = (this.data && this.data.quoteText) ? this.data.quoteText : ''


        this.wrapper.appendChild(this.quote)


        return this.wrapper 
    }

    static get sanitize() {
        return {
            quoteText: true,
        };
    }


    validate(data) {
        if (!data.quoteText) {
            return false
        }

        return true
    }


    save(blockContent) {
        const quote = blockContent.querySelector('.quote')
        
        return {
            quoteText: quote.innerHTML,
        }
    }

}


export const quote = Quote 

I will be very grateful for your help
