Offline size shown as "NaN MB"

Bug report

Today I opened devdocs.io on my browser and found many documentations have been updated. Okay, no problem, so I went to the "Offline" page and was surprised to see "NaN MB" as the size of each documentation. Okay, maybe I can uninstall all, refresh, install all, and it will be solved… Nope, even after uninstalling all and reinstalling all, it still shows "NaN MB".

OS information

Mozilla Firefox 108.0.1 (64-bit) on Manjaro Linux.

Steps to reproduce

Use devdocs.io on Firefox, and download offline documentation.

I have NOT tried on Chrome (yet).

I have NOT tried on a new Firefox profile.

I have NOT tried to empty all local storage and reload devdocs.io. I don't want to try it because I'm tired of re-selecting all the documentation every time I switch browsers, or every time the browser decides to delete devdocs local storage. Seriously, I lost count of how many times I've done that. I tried the red "Reset" link at the settings page, and this issue persists.

Possible fix

I don't know how to fix it.

To ease the pain, it would be awesome to store the devdocs settings and list of enabled documentations somewhere else. Maybe a manual import/export, maybe syncing on some remote server, well, something. But this wish is off-topic, as it should become a different issue. I just found out about #1818, and I had never noticed those Export/Import buttons before.

Seeing the same here on Chrome on Windows 11, along with all the documentation asking for an update at the same time, updating still leaves the NaN as the size

Same here, tested in Chrome 108.0.5359.124 & Firefox 108.0.2 on Ubuntu 22.04
