Trailing slash in base URL config -> bookmarklet 404

[nanocat-net]

I configured my linkwallet at https://lw.x.x/config and added a basedomain string of https://lw.x.x/. Clicking on the Bookmarklet link then opened a popup with a 404 error.

I changed the basedomain string to https://lw.x.x (without the trailing slash) and it works as expected.
