Table node: the class cannot be saved

[ChrisRegElec]

Current Behavior

@flowfuse/node-red-dashboard: 1.29.0
node-red: 4.1.2

I created a "CSS" template, and when I try to assign the class to the Table widget, it won't save.

Steps To Reproduce

To apply the CSS style, I have to assign it to the Group.

Environment

• Dashboard version: 1.29.0
• Node-RED version: 4.1.2
• Node.js version: 22.12.0
• npm version: 11.0.0
• Platform/OS: win10
• Browser: EDGE

Have you provided an initial effort estimate for this issue?

To clarify this, the bug is not to do with CSS, it is that a class specification in the config does not stick.
To replicate the problem

1. Create a Table node, configure a Group and deploy
2. Open the node and assign a class
3. Click Done, the Deploy button is not enabled
4. Open the node again, the class field is empty

if i inject msg.class="custom-table" into the Table node, it correctly applies the CSS Without applying the class to the group.
