Summary

Cannot see destination or flight details on kiwi.com with removed WebWorkers, both works with Strict protection on WebWorkers.

Setup

Pages affected: https://www.kiwi.com/
JShelter Version: 0.20

Default JSS level

OS: Tested in Linux
Browser: I replicated the failing behaviour both in Firefox and Chromium. I found one Firefox instance where I cannot reproduce the issue. Strict WebWorkers make the page run in all tested browsers.

How to reproduce

1. Go to https://www.kiwi.com/
2. Fill in flight details like departure location and destination and dates of flights.
3. Click Explore.

Expected result

Depending on the information inserted in step 2, you should either see locations (destination not set in step 2) or available flights.

Actual result

The structure of the page is created but details of destinations or flights are not shown. The page looks like it is waiting for missing data.

Reproducibility

I reproduced on two machines both in Chromium and Firefox. I found a Firefox (profile) where I cannot reproduce the issue.

Workarounds

The page works with Strict WebWorker protection in all tested configurations.
