Panel collapsedBreakpoint event does not fire

[iokom]

Framework7 Version : 5.7.14
React Version: 17.0.1

The panel event "collapsedBreakpoint" does not fire.

After i change line 171 in framework7/components/panel/panel-class.js from
setCollapsedBreakpoint(emitEvents) { to setCollapsedBreakpoint(emitEvents = true) { it works.

I tried this change, becaus in line 103 (setVisibleBreakpoint(emitEvents = true) {) it was implementd similar for the "breakpoint" event.
