HTML Object truncates randomly

HI Support,
I have previously run on Private instances and Pro version of Webpagetest but have the same issue on both, and also on the publicly available version.
I use the HTML object stream that is available from the Waterfall object stream and have found that the HTML stream gets truncated, especially for large HTML streams.

A particular example is on 220923_AiDc6S_AYN ( tested page - Here the first run object is complete, but the repeat run object is truncated at 626,652 bytes (expecting 818.9 KB (uncompressed).

Another example is even more bizaare. 220923_AiDcHG_7ZR is for Here the First view truncates at 365,265 bytes of 471KB. However, the Repeat view is completely damaged as it shows a random JSON result of approx 126KB.

These are just 2 examples among many I have found.

The use of this feature is of importance to me in my work, so would appreciate if you could resolve this.

Thanks in advance

Why has there been no response to this whatsoever either here or through my account support ticket?

I have 4 open tickets and none have received any response from support at all.

Is anyone else having similar support issues?
