If the TOC is soo long that it requires vertical ecrolling to select the wanted chapter/section the TOC is always reset to the top after a navigation tap.

That the TOC after clicking stays in the same position.
Open the Phing-Manual at
and open some long chapters (for example "Optional Tasks") and scroll down and tap a section. The section will correctly load in the right frame but the TOC will be scrollled back to the beginning.
This output rendering was done with the built-in stylesheets in Oxygen 13.2 (and not the off-the-shelf 1.76.1 sheets - but the same effect can also be observed with the plain 1.76.1 sheets)
