Browser storage use by

Is anyone else seeing enormous local storage by

In mobile Chrome (I know, possible heresy here of all places :slightly_smiling_face:) it’s rocketing up around 30 Mb per page view. Recently I cleared storage for the site (it was reported at ~1.6Gb!) and yet within a very short period it was bank at 500Mb+.

I’ll see if I can reproduce on mobile Firefox but wanted to check if others saw this too.
