[Question] Undo manager and setStyle

[iamkeiryan]

hi @artf,

I have created a custom style manager that uses setStyle to update css in the canvas. Whenever I try to undo it after a single change, the css are getting removed completely. I haven't dig deeper yet with the undo manager and was hoping that this is a configuration issue.

Here's the edited canvas:

Here's what happens after undo:

I'm using the editor?.runCommand('core:undo'); command.

Edit:
Upon checking the details, the css is getting removed completely whenever I checked the editor.getCSS. Haven't found a solution on what causes this.
