Firstly, I have checked with combinations of the Core and the plugin. I found it only seems to happen when using the plugin. I am suspecting may be related to something that is in the plugin which are not yet merged into the core?

Secondly, it seems to happen only on new paragraph. Not on existing paragraphs.

Thirdly, as others reported, these were only reproduced in Chrome 78.0.3904.9 and 78.0.3904.87
Not in Safari (13.0.3) nor Firefox (69.0.1).

Tested in Mac OS 10.14.6. IME is ATOK.

I am going to restate the exact process which @torounit has written at the top. Because it seems to be very precise to reproduce it.

1. Paragraph block. Type something using IME, and press confirm key (e.g. space key) to confirm at the end.
2. Hit Return key, to start a new paragraph.
3. With or without typing anything, hit "delete" key. Which should move the cursor back to previous paragraph.
4. start typing something using IME, and press confirm key. This should cause the error, as reported above.

Notes:

• At 3. hit "delete" key. If you hit "left" key -- which will only move the cursor back to previous paragraph block, without deleting the new paragraph block -- error does not occur. Even if you start typing something, as long as you go back by hitting delete key, it occurs.
• Error only seems to occur on the block that is located at the bottom of the content. It does not occur on already written paragraphs that are not at the bottom, or newly inserted paragraph in the middle of the content.

5.2.4 + GB 6.8.

173 = Enter, to go to new paragraph
179 = Backspace, to delete the new paragraph and go back to previous.
258 = Enter, to confirm the change → this moves the caret to the beginning of the paragraph without pasting the entered text.
