Edge Event error!

[Lukasss93]

This error is shown only on Microsoft Edge for Windows 10 Mobile.
It is a MUI bug or Edge bug?

SCRIPT5007: Unable to get property '_muiEventCache' of undefined or null reference
mui.min.js (1,7975)

Please answer me asap :)

@Lukasss93 Thanks for the bug report! I can take a look at this tonight.

@Lukasss93 I wasn't able to reproduce the error looking at the documentation site (https://www.muicss.com) on Edge/Win10. Are you seeing the error on the documentation site or with your own code?

I can see where the error would be triggered but I need to see an example to determine why a null value is being passed into the function instead of an HTML Element:

Sorry, I forgot it!

Now this are the steps to replicate the problem:

1. Open Microsoft Edge on Windows 10 PC
2. Visit my web site on https://api.auraxstudios.com/
3. Open Developer Tool F12
4. Click on Emulation Tab
5. Select on:
   Browser Profile: Windows 10 Mobile;
   User Agent String: Microsoft Edge - Windows 10 Mobile;
   Orientation: Landscape;
   Resolution: 1920x1080;
6. Reload the page
7. Click on Console Tab, ignore XHR bootstrap error, now click on a item menu.
8. In console will be shown this error:
   SCRIPT5007: Unable to get property '_muiEventCache' of undefined or null reference
   mui.min.js (1,7975)

This bug is shown ONLY on this Browser WITH that parameters.
I have replicated it on PC (see top ^) and on my Nokia Lumia 1520 with Windows 10 Mobile Insider Preview 10.0.10586.63 Version 1511.

PS. On my Nokia Lumia 1520 works fine with Portrait and fail with this bug with Landscape... :( WTF

Thank you for your support.

@Lukasss93 Thanks for your excellent bug report! I was able to use the Edge debugger to step through the code and identify the problem. It turns out that it was a bug in MUI triggered when mui.overlay('off') was called before mui.overlay('on'). The switch to Windows Mobile triggered the part of your code that called mui.overlay('off'). In any case, the bug is fixed in v.0.2.10:

Let me know if you're still seeing the error. BTW your site looks great!

Very thank you for your support! Now it works fine.
