Awesome! That was some really fast work. I'll try it out next week.

All this development happened before I joined the team, so I'll
request the previous GDP team to kindly shed some light here.

I think that would be a good temporary workaround until we figure out
the real issue and how/when to solve it completely. Could you please
create a jira ticket for this issue with all the info you have at
hand? Also please link to the ticket in a FIXME comment in your code
where you hardcode the size. Thanks.
