Strange behavior offline + online editing

Strange behavior when editing text online and offline at the same time
I ran this demo https://github.com/BitPhinix/slate-yjs-example

Fixed in slate-yjs 0.1.3

@BitPhinix I tested the demo again, the error repeats exactly the same

Hmm weird, I'll recheck this again asap.

This bug also occurs when you change selected mark at some part of text and refresh page.
And one more bug, i can't select more than 1 mark marks on one line, weird thing...

I took a look at this today and the root cause is the way the split_node operation is translated.

Let's say we have 2 clients with the same state (a paragraph with the text hello world):
{type: "paragraph", children: [{ text: "hello world"}]}

Client 1 performs a split_node operation inside the paragraph with offset 5 this results in the following operations:

• remove text " world" from [0, 0]
• insert new text node containing " world" at [0, 1]

Client 2 simultaneously performs a split_node operation inside the paragraph with offset 6 this results in the following operations:

• remove text "world" from [0, 0]
• insert new text node containing "world" at [0, 1]

If the clients are now synced the remove text operations will be combined and both insert node operations will be applied resulting in both the "word" and " word" text nodes to be inserted. YJs can't know that the new nodes are a result of a split_node operations.

slate-collaborative has the exact same issue cudr/slate-collaborative#29. I'll try to find a solution as soon as I find the time to or just port over the solution of slate-collaborative if they manage to solve it.

Closing this issue because this is the intended behavior. For more details refer to: https://discuss.yjs.dev/t/modeling-slate-split-node-behavior-in-yjs/283/2
