Issue Summary:

When editing a table embedded in a ollapsible on a custom page in Guru, the table editing functionality exhibits unexpected behavior. Specifically, copying a row and pasting it into a new row within the table results in the first cell of the new row being replaced with a collapsible instead of retaining the copied text.

Use Case:

My team actively maintains a Release Schedule table on a custom Guru page. This table is stored within a collapsible for organization and easy navigation. The content of this table is updated frequently, often requiring us to copy and paste rows to ensure consistency. The described behavior disrupts the workflow and causes confusion, requiring additional steps to manually correct the row content.

Steps to Reproduce:

1. Navigate to a custom page containing a table within a collapsible block.
2. Copy the content of an existing row in the table.
3. Paste the copied content into a new row.
4. Observe that the first cell of the new row displays a collapsible instead of the copied text.

Expected Behavior:

Pasting a copied row should replicate the original content accurately across all cells, without altering the structure of the table or introducing unexpected elements like collapsibles.
