snapshotToDoc very slow with large snapshot

[kerituni12]

The performance is slower due to the use of nextTick in the _snapshotToBlock method. Specifically, I see the following code:

await new Promise(resolve => nextTick(() => resolve(undefined)));

While nextTick is useful for handling large content during pasting, it can slow down operations when used in snapshotToDoc. It would be beneficial to add a parameter like usingNextTick to snapshotToDoc or explore other approaches to mitigate this issue.

We are encountering the same issue. Can we proceed with removing the nextTick line?
Please let us know if there are any potential consequences of doing so.

I'm also facing this issue from recent days. Don't we have any fix for this.

我也遇到了这个问题，希望在json的处理上能够更优秀，这样就有更通用的语言，可以被更多项目使用
