I want to know the details how they achieved it (the support for super-long paragraphs, or rather, the absence thereof).
Does anyone know?

Pretty short change for reducing O(n^2) impact with a cache.
This change includes the following scalability improvements for documents containing extremely large paragraphs:
- Reduces the size of layout contexts to account for LF control chars.
- Due to typical access patterns while laying out paragraphs, VCL was making O(n^2) calls to vcl::ScriptRun::next(). VCL now uses an existing global LRU cache for script runs, avoiding much of this overhead.
I lack the context - are they still layong out the widths of characters when wrapping?
... by the LibreOffice devs in Indo-European-speaking countries.
So long as LibreOffice could not handle long paragraphs there was essentially no free tool to publish Tibetan.
