WordsProcessing: PdfFormatProvider: Slow PDF export when measuring nested tables

When measuring nested tables and the levels are more than 5 level, the export is very slow.

Hello,

With the upcoming Q4 2024 Telerik Document Processing Libraries release, a new timeout mechanism for importing and exporting documents will be introduced. The FormatProviders' Import and Export methods have a mandatory TimeSpan? timeout parameter, after which the operation will be canceled.

Hello,

I would like to put some additional information about the use case when performing additional testing with different HTML files. After the 5th level of nested tables, the PDF export becomes considerably slower. The application may be stuck into an endless loop and the application may hang.

We will do our best to optimize the export functionality with nested tables accordingly. Please excuse for the inconvenience caused.

I would like to point out that this is quite a critical bug. In other cases, the library would throw an exception, which we could catch and handle. However, in this case, the app will just hang.

Short of using a timer and cancel the export operation after some time (thanks to Dimitar for that suggestion), we are stuck. The timer option is a messy one, and not really something we should need to do.

Thanks
