drag

Describe the bug

When using the Swap plugin, it's impossible to cancel a swap once the swap threshold has been met for an item. You can't drag the item back to its original place to prevent a swap. This happens with or without the revertOnSpill: true option.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sortablejs.github.io/Sortable/#swap
2. Drag "Item 1" to h

I'm trying to replace the background diagram-maker canvas svg, with custom small circular nodes. So, probably this lead to more than 5000 number of circular nodes.

A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behaviour:

1. Go to 'Homepage demo'
2. Scroll down to "Connected lists"
3. You can see in the white list nested child limit 3 but I can drag 4 items inside the list. I have the same bug in my site, I set option maxItems

• Fresh laravel instalation
• Install laravel-schematics
• Open http://localhost:8080/schematics
• Click to edit default User model
• Do not change anything and just click on save.
• That action updates User model with all fields as "fillable".
• Not necessary we want to add fields on "fillable" list, on that model

After #1109 we do not need the whole JQuery anymore, we should use the lightweight Zepto as a drop-in replacement

Zepto is 9.6K

JQuery is 84K

The sorting does not seem to be working when the items are in a fixed height container that scroll all the items.

See this fiddle:

If you try to drag the last item in the list to the top it won't scroll automatically and even if you use the mouse wheel to scroll while dragging it, dropping it on the top won't trigger a drop.

I guess this has something to do
