Two tooltips on webpage, one default, one formatted with css

I have temporarily addressed this by editing glossify-link-html.twig and glossify-link-html.twig and replacing 'title=' with 'data-definition=' but this does mean there's no fallback browser tooltip if the css doesn't load.

Please reopen when you are able to provide more details.

I believe the OP was having an issue in their theming, where they were providing a tooltip using css, while the title attribute in the markup means the browser provides a tooltip too. Hence two tooltips.

My suggestion above fixes this, they simply have to use the 'data-definition=' attribute instead of 'title=' and the browser tooltip will be no more.
