What is the issue/comment/problem?

This issue is based on Antonio's suggestion on this line.

For context, I've noticed some weird behaviour when by mistake added two pyscriptjs script tags. The splashscreen errored out in a strange way because the element was already created.

Ideally we should detect if the user has two script tags pointing to pyscriptjs and throw an error saying that one should be removed.

late to the party ... current PyScript is based on sticky-module exactly to address these cases ... first comes first serves, the module will always try to grab its features from the sticky-module counterpart, no matter how bundlers will try to change that ... it's in the core of the project now (it's been weeks but ... hey ...).

Closing unless anyone is able to reproduce this issue again with current PyScript (in that case, please do re-open this issue!).
