Application#scrollToHash doesn't call decodeURIComponent. In practice, I'm not sure this matters for TypeDoc's use, since all of the fragments TypeDoc generates go through the Slugger, which turns % into _... I did a bit of searching of the spec, and couldn't find anything about this being necessary - why do we decode here?

Oh my bad that decode wasn't necessary, it's just duplicated logic since it already exists in Application#scrollToHash.

What was broken
Tapping an anchor link in the mobile sidebar menu updated the URL hash but didn't scroll to the target.
Root cause
.has-menu body { overflow: hidden }is still active when the browser tries to do its native scroll-to-hash, since Toggle.ts doesn't close the menu (and lift the scroll lock) until a 250ms setTimeout later. By then the native scroll opportunity has passed.Fix
Toggle.ts now manually calls
scrollIntoView()on the target after closing the menu, instead of relying on the browser's one-shot native scroll.Testing
Verified on [device/browser] that tapping sidebar anchors now scrolls correctly.
