leaflet1.91 Cannot read properties of undefined (reading 'setAttribute') at e._setAriaDescribedByOnLayer

i use

        marker.bindTooltip like this
        marker.bindTooltip("<a class=\"" + c + "\" href=\"" + r + "\" title=\"" + n + "\">" + n + "</a>", {
            permanent: true,
            interactive: true,
            direction: "top",
            className: "tip"
        })

it works perfectly with leaflet1.71

with leaflet 1.91 on canvas i get

Cannot read properties of undefined (reading 'setAttribute') at e._setAriaDescribedByOnLayer

it work if i dont put my markers on canvas

or

if in this part of leaflet1.91

        openTooltip: function (t) {
                    return (
                        this._tooltip && this._tooltip._prepareOpen(t) && (this._tooltip.openOn(this._map)                      
                        , this.getElement ? this._setAriaDescribedByOnLayer(this) : this.eachLayer && this.eachLayer(this._setAriaDescribedByOnLayer, this)                                         
                        ),
                        this
                    );
                }
