Is this a bug report or feature request?

🐞 Bug report

💻 Version of CKEditor

CKEditor v5 @ 12.3.1

📋 Steps to reproduce

Currently you're able to indent the table, but it applies the indentation to both the table element and each cell's paragraphs separately.

1. Open the indent-block manual test.
2. Insert a 2x2 table.
3. Fill the cells with some random text.
4. Select an entire table.
5. Increase the indentation using toolbar button.

✅ Expected result

One of two:

• Only the table gets indented.
• Indentation feature is disabled for tables.

❎ Actual result

Both table and all the cells gets indented.

Markup:

<figure class="table" style="margin-left:40px;">
	<table>
		<tbody>
			<tr>
				<td>

					<p style="margin-left:40px;">aa</p>
				</td>
				<td>

					<p style="margin-left:40px;">bb</p>
				</td>
			</tr>
			<tr>
				<td>

					<p style="margin-left:40px;">cc</p>
				</td>
				<td>

					<p style="margin-left:40px;">dd</p>
				</td>
			</tr>
		</tbody>
	</table>
</figure>

Looks like the same bug as ckeditor/ckeditor5-indent#8 - the items on which command is executed are not filtered.

It's a different block - the command should check isEnabled for a top-most block from the selection.
