Flickity previous and next buttons not fully accessible (according to WAVE tool)

Heya!
According to this tool ([https://wave.webaim.org/]), both the next and previous buttons are, even though there's an SVG generated and labelled with ARIA nomenclature, considered empty and a possible problem for people relying on screen readers.

Would it be a possible solution to add a title tag to the SVG itself so it may be considered well-formed and readable again?? I.e. for the "previous" button:

```

```

Search the JavaScript source for the flickity-button-icon SVG and the previous/next button markup, then reproduce the report with the WAVE tool. Done means both controls and their generated SVG content are recognized as meaningful and accessible by screen readers without losing the existing Previous and Next labels.
