When the html contains inline data elements such as audio, doc.outerHtml() function takes a very long time (more than 2 mins). The inline audio is present as data in base64 format of the form:

<audio controls controlsList="nodownload" src="data:audio/mp4;base64,...">Audio playback is not supported. Please try with a different browser.</audio>

Is there something that can be done to reduce this time to extract the outer html? The audio data itself is less than a couple of MB in size.

I think this is performance issue, i will work to find a solution.
