When running a PDF export I'm getting the following error:
[SEVERE] webpack-internal:///./src/scheduler/feature/PnPDFExportFeature.ts 209:32 TypeError: Cannot read property 'top' of undefined

The error seems to happen ever since we upgraded from 4.0.8 to 4.2.6.
I'm however not able to reproduce a test case. Weirdly the error also seems to only occur while running a Selenium test.
I saw the same issue on github already but I don't think it was fixed.
