How to control the execution order of inputTransformation event listeners?

[bkosborne]

I've written a simple plugin that strips all <span> and <div> elements from pasted HTML. I do this because when people paste content from sources like Google Docs or MS Word, lots of empty spans and divs can be created. However, I want to ensure that my plugin's event listener executes after all others. I see that I can set a priority for the subscriber, which defaults to "normal". But, if I change it to "lower" or "lowest", it doesn't execute at all.

Here's the code:

this.editor.plugins
      .get("ClipboardPipeline")
      .on("inputTransformation", (evt, data) => {
        const writer = new UpcastWriter(data.content);

        // Scan all divs and spans and save them for later removal.
        let elementsToUnwrap = [];

        const range = writer.createRangeIn( data.content );
        for (const value of range) {
          if (value.item.is( 'element', 'span') || value.item.is( 'element', 'div')) {
            // We can't just unwrap it here, as it seems to affect the scan
            // for other elements.
            elementsToUnwrap.push(value.item);
          }
        }
        for (const item of elementsToUnwrap) {
          writer.unwrapElement(item);
        }
      });

I believe my event listener is executing before the Paste from Office plugin.
