Selecting a chapter from the TOC moves the text but the audio stays where it was (web reader and iOS)

In both the experimental web reader and the iOS app, tapping a chapter in the table of contents jumps the reader view to the right chapter, but the audio stays stuck at its old position instead of following. Navigating within the text by tapping sentences works fine.

Resolution: This is current expected behaviour rather than a broken install. The TOC entries of an aligned EPUB are bare xhtml hrefs (OEBPS/fileNNNN.xhtml) with no #fileNNNN-sM fragment, and the audio-seek code in both clients needs a fragment to resolve a SMIL clip: the web reader's getClipForLocatorMultipleAudioForOneHtml early-returns when locator.locations.fragments.length === 0, and the iOS BookService.getClip does guard let fragment = locator.locations.fragments.first else { return nil }. With no clip resolved, no seek is ever issued, so the player never moves. Workaround in both readers: after jumping to the chapter, double-tap or double-click almost any sentence in the reader pane -- sentence locators carry the fragment, so the audio seeks there. A real fix would resolve each TOC href to its chapter's first SMIL <par> id when the TOC locator is built, so the existing seek path finds a clip.
