Problem with font tag

[allphat]

hello,

I have developed a custom plugin to manage my editable nodes in a template. each editable node has a specific class.

so I came up with this plugin:

    editor.DomComponents.addType('tpl-content', {
        isComponent: el => {
            if (el.classList) {
                if (el.classList.contains('tpl-content')) {
                    return true
                }
                return false;
            }
        },
        model: {
            defaults: {
                draggable: false,
                droppable: false,
                badgable: false,
                editable: true,
                highlightable: false,
                selectable: true,
                propagate: ['highlightable'],
                styles: ".tpl-content { border: 2px dashed lightgreen }",
                attributes: { 'contenteditable': true },
            },
        },
        view: {
            events: {
                focusout: 'onDisable',
            },
            onRender({ el }) {
                el.contentEditable = true
            },
            onDisable() {
                const { el, model } = this;
                if (el.innerHTML.trim() !== '') {
                    model.components().reset([{
                        type: 'text',
                        content: el.innerHTML
                    }]);

                }
            },
        }
    })
}

it works well for every kind of nodes (span, td, p,...), but for font tags, the edtior seems to crash (browser tab irresponsive but no errors appears in console).

I replaced the standard editor with ckeditor4.

is there a specific constraint on font tags?

I'm not sure that is related to the core but a reproducible demo might help

I tested with some old templates. I will never have this case. so we can close it.
