After update to 1.33.0 loading tabs/cols sporadically ends up with blank page

Still haven’t fixed the issue and I still think it is a streamlit problem probably based on some concurrency jobs or nested pages in the background.

What I’ve found out - the code runs w/o tabs, but when I introduce the tabs then I just get a blank page.

I tried all major versions between >1.26.0 and all have this problem. In 1.27.0 there were some bug fixes in st.tabs, probably here were the new bugs introduced!
