Thanks so much for flagging this, after some testing on my side and discussions with the engineers, we think that this bug is likely related to the way Vanadium handles iframes. As our donation flow is connected to a secure third party donation service that uses iframes to serve this modal, I fear that we're going to have to consider this bug for GrapheneOS + Vanadium users an edge case and close this ticket for now.

We have documented this in our internal docs for consideration and future roadmap planning around fundraising
