BUG-1 (CRITICAL): messages.js line 522 — mismatched quote in
setComposerStatus('Reconnecting…') caused JS syntax error on the
reconnect path.
BUG-2 (HIGH): messages.js line 491 — broken template literal
'\\n\\n*{d.hint}*' restored to '\n\n*${d.hint}*'. Error hint
text was non-functional (missing $ prefix and escaped newlines).
BUG-3 (HIGH): messages.js — showApprovalCard(pending, pendingCount),
_approvalCurrentId, and approval_id in respondApproval() were removed,
regressing the simultaneous approval queue fix from PR #546. Restored
all three, including the '1 of N pending' counter and poll passthrough.
BUG-4 (LOW): api/streaming.py — MiniMax thinking delimiter regex
missing closing pipe: <|channel> -> <|channel|> in both
_strip_thinking_markup() and _looks_invalid_generated_title().
ALSO: test_issue487b.py docstring changed to raw string to fix
DeprecationWarning for invalid escape sequence '\s'.
Bug: the autolink pass stashed <a> tags (via _al_stash) before running,
but did not stash <img> tags. When  was converted to an <img>
tag by the image pass, the subsequent autolink regex matched the URL
inside src="..." and wrapped it in <a href="...">url</a>, producing
src="<a href="...">url</a>" — a completely broken image source.
Fix: extend the _al_stash regex from:
(<a\b[^>]*>[\s\S]*?<\/a>)
to:
(<a\b[^>]*>[\s\S]*?<\/a>|<img\b[^>]*>)
This stashes both <a> and self-closing <img> tags before autolink runs,
then restores them after, so the URL inside src= is never touched.
Adds 7 regression tests in tests/test_issue487b.py.
