"import into note" from zip look like lost data or content display confusing

[dolt131943]

Relate trilium and OS vesion: 0.45.10, macOs bigSur 11.2.1

I use "import into note" import a zip that export from trilium notes.

It look like lost data or some content display confusion.

orginal document:

after create new note and import to root, that shown different and look like different note display same content like one note:

new db and import log: trilium-2021-02-22.log

This may be not the import problem. maybe the content display problem.

Sometimes it can also trigger this problem when I use original db (not import one),

reproduce step like this but not necessarily:

1. open a note, input some text;
2. Suddenly unable to input a new line, but can edit exists text , but cannot save; (like a bug)
3. now switch to other empty node, it will always show same content like last edit.
4. if edit this content , will not be saved.
5. reopen app or close current tab will solve this problem.

I have found those message in log, maybe the reason : 17:17:28.981 JS Error: Uncaught error: Message: Uncaught CKEditorError: split-operation-position-invalid Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-split-operation-position-invalid, URL: http://127.0.0.1:37840/#root/fWPOM4NiHaiE/f8Mw1msWqYjm/EfSLIqjkuUcL/JbHYgD1KiCvm-e36U, Line: 5, Column: 7462, Error object: {"name":"CKEditorError","context":{"baseVersion":104,"splitPosition":{"root":"main","path":[9,18],"stickiness":"toNext"},"howMany":-17,"insertionPosition":{"root":"main","path":[10],"stickiness": "toNone"},"graveyardPosition":null,"__className":"SplitOperation"}}, CKEditorError: split-operation-position-invalid Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-split-operation-position-invalid at el._validate (<anonymous>:5:331273) at Fl.on.priority (<anonymous>:5:371012) at Fl.fire (<anonymous>:5:128716) at Fl.<computed> [as applyOperation] (<anonymous>:5:157962) at ol.split (<anonymous>:5:337629) at K_ (<anonymous>:5:770830) at <anonymous>:5:770552 at <anonymous>:5:770728 at Fl.change (<anonymous>:5:371639) at U_.execute (<anonymous>:5:770326)^M Stack: Error at Object.w [as logError] (http://127.0.0.1:37840/app-dist/desktop.js:1:77260) at window.onerror (http://127.0.0.1:37840/app-dist/desktop.js:1:290039) 17:17:29.118 JS Error: Uncaught error: Message: Uncaught CKEditorError: split-operation-position-invalid
