[BUG] Crash when pasting in rich text

[acook]

Describe the bug

Hard locks all of Obsidian if you happen to put certain types of rich text into the table editor.

To Reproduce
Steps to reproduce the behavior:

1. Copy data from a Google Sheet
2. Paste it into a field in the table editor
3. Click copy to markdown

Expected behavior
Preferably, it would take the pasted table and parse it and put in the correct data in rows and columns.

Actual Behavior
Dumps rich text into a single cell and locks up Obsidian.

Desktop (please complete the following information):

• OS: Linux Solus
• Version: Obsidian 1.1.16 Markdown Table Editor 0.3.1

Additional context
Haven't tested with other rich text sources than Google Sheets.

I restarted Obsidian and the Markdown Table Editor sidebar popped up next to the normal sidebar. 2 sidebars!
