Page builder not working in IE 11

Hello,
Page builder ck is not working with Internet Explorer 11. In normal article editor tabs like "Images and links", "Options", "Publishing" and so on are missing. Tabs shows correctly when i disable Page Builder extension. Also it is impossible to edit articles created with Page Builder as content does not appear, sidebar menu is hiding buttons and you cannot collapse it. Also "Close" "Save and close" and other buttons are not working and you cannot exit Page Builder editor(you must hit back button on browser). I attached some images to explain better. Page builder is instead working ok in Firefox and Chrome. I tested this in joomla 3.6.2. and 3.6.4 and also in a clean install (with only t3 framework installed).
Can you help with this?
Thanks!
Matteo

Hi
thanks for reporting the issue. That is right, IE 11 does not support the for/var JS method ...

I will try to find a fix. Remind me next week if I don't come back to you

Hello,
I did a quick check. Now normal articles are ok with all the tabs that were missing. But there are still some problems editing articles created with page builder. For example in a two columns text layout columns have wrong width, they are too wide (maybe each of them has full screen width) so you have to scroll to the right to be able to see the right column of text. Then when you enter the edit screen for this right column the black bar above (with validate and cancel buttons) is missing, so you cannot apply changes. I don't know if this is a styling issue or a javascript problem. I attached some images to explain better.
Thanks for your help.

please remind me at the middle of next week
