Block dragging does not trigger automatic page scrolling

[MrKarlDilkington]

When dragging blocks up and down a page, the page is not scrolling automatically. This problem was reported in a closed issue, so I created a new issue to make sure it doesn't get lost.

This issue affects concrete5 5.7 and 8.

Block drag scrolling is broken in:

• Chrome
• Firefox
• Opera

Block drag scrolling is working correctly in:

• Internet Explorer 11
• Edge 16

Strangely, Safari appears to work just fine as well.

I can confirm it doesn't work in Chrome and Firefox

@aembler

This issue appears to affect any moving in edit mode, including moving blocks and layouts. Scrolling the page now requires using the scroll wheel, up/down arrow keys, or page up/page down keys while dragging.

Based on the browsers affected (Chrome is the most popular browser) and how much it affects the editing experience, can we relabel this to "priority:must have", please?

Hey folks,

first time contributing to concrete5.

I looked into it today and did some debugging but couldn‘t find the cause of the problem.

Every hint or piece of information regarding this issue appreciated.

Will further look into it.
Thanks!
