[REACT] PDF Export Missing Cells

Forum post

Hi Bryntum, I hope this finds you well

I've been thoroughly debugging why a customer's gantt PDF export will show the task names beyond a certain row as blank. Its actually an intermittent issue, fails 3 out of 4 tries. I was curious and tried adding a 5 second wait 'onBeforePdfExport', but the result was the same.

I compared against your examples, and was able to find the breaking difference. The issue only happens when the request HTML has task name classes like 'b-react-portal-container', and these only happen when we use a custom 'TaskNameRenderer' in 'Columns.js'. Is it possible there is an upstream bug with React portals and PDF export?

Issue persisted with a simplified 'TaskNameRenderer' that just returned a span. We need the custom 'TaskNameRenderer' to satisfy business logic with links.

Could you please help direct me to not face this issue, whether that be fixing upstream or a workaround like forcing TNR not to use portal or simple rendering them 'onBeforePdfExport'?

Many thanks, Ben
