PageFrontEdit toolbar not always showing up

[modifiedcontent]

PageFrontEdit would be perfect to use in production, but I see the module is still on version 0.02. Is it actively developed?

When it works it is perfect, but the edit toolbar doesn't always show up. Chrome seems to work best, but in Firefox and IE/Edge I only get the save and cancel buttons and then when you try to save changes you get an ugly error pop-up 'No changes to save'.

Has anyone else seen this? Is it a known problem? Maybe a js/jquery conflict? Should I install other editors - if that is possible?

And is it supposed to work on mobile? Double tap? Or maybe just not on my crappy phone...

Edit: I have now seen the toolbar show up on IE/Edge, but it is hit or miss. When it doesn't show up and you click cancel and try again, you get the toolbar on the second attempt. Is there a way to make sure the toolbar loads? Move javascript to another place?
