Description
I tested the file from https://vaadin.com/forum/thread/17814053/hello-i-have-problem-with-certain-xlsx-files-when-read-it-s-infinite-and and the spreadsheet seems indeed to get stuck(I let it run for 15+ minutes) - yet printing the content out with POI (4.1.0) works without issues. I tested with Spreadsheets 2.1 and 3.0.0.alpha1. No exceptions were thrown.
Fully working example attached.

Research direction
Start by reproducing the hang with the attached sheet-test.zip file and compare the behavior with Apache POI 4.1.0, which can print the file successfully. Trace the spreadsheet loading path for this XLSX and determine what completion should look like: loading finishes without exceptions or an indefinite wait.
