The text styles are being reset when a line break is inserted about tiptap-text-direction

Hi @thisunravisara

Thank you for reporting this.

I'm looking into it and will let you know when I found a solution.

I spent a couple of hours to find the issue but it doesn't seem to be a bug in my plugin. The default behaviour of ProseMirror is to remove all marks from the previous line when entering a new like, as you can see in their basic example. Maybe TipTap is doing something that I'm not aware of.

@thisunravisara I can't find any documentation pointing setNodeAttribute resets marks. But your solution works. Thank you.

I released 0.3.1 to fix this issue.

Hi @amirhhashemi

Thanks a lot for the speedy reply!

You can find out the problem by toggling the extension on and off over here: StackBlitz Link.

Yeah, it appears that Tiptap has indeed enhanced the default behaviour of ProseMirror.

Hi @amirhhashemi

Have to preserve and restore marks after updating node attributes

addProseMirrorPlugins: function( this ) {
                        return [
                            new Plugin({
                                appendTransaction: ( transactions, oldState, newState ) => {
                                    const docChanges = transactions.some( transaction => transaction.docChanged,
                                    );
                                    if ( !docChanges ) {
                                      return;
                                    }
                                    let modified = false;
                                    const tr = newState.tr;
                                    newState.doc.descendants(( node, pos ) => {
                                      if ( this.options.types.includes( node.type.name )) {
                                        if ( node.attrs.dir !== null && node.textContent.length > 0 ) {
                                          return;
                                        }
                                        const marks = tr.storedMarks || [];
                                        tr.setNodeAttribute( pos, 'dir', getTextDirection( node.textContent ));
                                        marks.forEach( mark => {
                                          tr.addStoredMark( mark );
                                        });
                                        modified = true;
