Classic block: pasting content replaces the entire block

[ha-un]

Quick summary

When using a text expander software or shortcut in the Classic block, the block itself is removed and the text that is inserted using the text expander is added through a Paragraph block.

Steps to reproduce

1. Add a Classic block
2. Write a few sentences/words
3. Insert a line using text expander

What you expected to happen

For the text added through the text expander to be added in line of existing text or block

What actually happened

The entire Classic block (and text already added to the block) is removed. The text inserted using the text expander is added as a Paragraph block.

This does not happen when adding it without using a Classic block. Works in the same sentence/row as well.

Impact

One

Available workarounds?

Yes, easy to implement

Platform (Simple and/or Atomic)

Simple, Atomic, Self-hosted

Logs or notes

The workaround would be adding text using the Paragraph block and then copying & pasting it to the Classic block. However, this would disrupt the writing flow if a user is already writing inside the Classic block.

I encountered another issue where a user is unable to paste any text into the Classic Block without it automatically converting to the contextual modern blocks, such as the Paragraph Block. I attempted to replicate the problem on my end in various ways but was unsuccessful. However, the user can consistently replicate the issue.

The only difference between my testing and the user's is that I'm using a Mac, while the user is using a Windows machine.

P.S.: The user recently discovered that if they use the contextual menu in the editor to copy and paste, the Classic Block does not convert. However, when using keyboard shortcuts, the issue consistently occurs for them.

Steps they take (and they can see the issue, but I cannot replicate):

1. Copy text from another location (webpage or Word, etc.)
2. Create a new page/post
3. Add the Classic Block
4. Paste using keyboard shortcut

@liviopv any chance you can check and try to replicate this?

Marking as Closed since 18.5 is now running on Simple and Atomic.

Reopening as this is not resolved. I was able to replicate on user's site from this report: 8415063-zd-a8c.

Specifically using a text expander to add the content to the existing Classic Block.

I'm still able to reproduce this:

Noting that this only happens when the Classic Block is inline (no iframe). When the Classic Editor block is loaded with the pop-up, it works correctly.
