Test-coverage expansion (2-agent reviewed, both SHIP). The named candidates
(roomToUnread, markedUnread, serverAcl, plaintextCaches, recent*) were already
tested, so this targets genuinely-untested pure logic.
- dom.test.ts: getThumbnailDimensions (scaling math incl. just-over-cap
boundaries), tryDecodeURIComponent, syntaxErrorPosition, and the three
scroll-view geometry helpers (via duck-typed element mocks — no jsdom).
- emoji.test.ts: getHexcodeForEmoji (astral codepoints, 4-digit zero-pad,
FE0F/FE0E/200D stripping on and off, keycap sequences, degenerate inputs)
and the pre-load `undefined` contract for getShortcode(s)For.
Fix (found while writing the tests): syntaxErrorPosition required whitespace
AFTER the digits (`/position\s(\d+)\s/`), but real V8/Node JSON.parse errors
put the number at end-of-string ("... at position N"), so it returned
undefined for every real error and the three dev-tools JSON editors silently
pointed their cursor at position 0. Dropped the trailing `\s`; tests now assert
extraction at end-of-string.
Gates: tsc 0, eslint 0, prettier clean, 891 tests, build ok.
