No longer working with chromium 75 with dev tools open

It's been causing warning about deprecated stuff for a while, but with chromium 75 it is causing javascript errors:

Uncaught (in promise) DOMException: Failed to set the 'innerHTML' property on 'ShadowRoot': The provided markup is invalid XML, and therefore cannot be inserted into an XML document.
at XMLDocument. (file:///home/user/.config/chromium/Default/Extensions/kkelicaakdanhinjdeammmilcgefonfh/2.6.3.2090_0/scripts/enable-tooltip.js:95:34)
