Setting style attribute on table makes messed up value

[lean-jeremy]

📝 Provide detailed reproduction steps (if any)

I use setAttribute to set both the class and style of a table.

editor.model.change ( writer => {
      writer.setAttribute("class", "test", table)
      writer.setAttribute("style", "background-color:Tomato;", table)
});

✔️ Expected result

<figure class="table test" style="background-color:Tomato;"> 
   <table>
...

❌ Actual result

The actual result has this weird string for the style value. I can see some similarity/pattern ("2:c;3:k;4:g;5:r;6:o;7:u;8:n;9:d;" = ckground?)

<figure class="table test" style="0:b;10:-;11:c;12:o;13:l;14:o;15:r;16::;17:T;18:o;19:m;1:a;20:a;21:t;22:o;23:;;2:c;3:k;4:g;5:r;6:o;7:u;8:n;9:d;"> 
   <table>
...

❓ Possible solution

Perhaps there is something wrong with the style conversion?

editor.conversion.attributeToAttribute({
    model: "style",
    view: modelAttributeValue => {
        key: "style"
        value: modelAttributeValue
    }
})

I appreciate any help 🙏

Disregard my previous comment. I didn't notice this is a model change.

I think I saw a report regarding trying to keep the entire style of an element in the model as a style attribute. It should certainly be convertible.

Probably you refer to this one @Reinmar: #4517.

@Reinmar @Witoso
Thank you very much for the help 🙏, I've had luck using Reinmar's workaround here.

Now the style is converted properly. This fits my goals, so this ticket can be closed but I'll leave that up to you since #4517 seems to be ongoing.

Glad it helped, please +1 the #4517, and I will close this one :)
