Reference links, footnotes, unsupported HTML, and oversized files park
markdown edit tabs in Source mode with a banner, but the dedicated
read-only preview was reachable only through a menu item and a
shortcut. Add Preview to the view toggle and to the banner for exactly
this case, reusing the existing preview tab instead of duplicating it.
Bold wrapping a code span came back inverted: ``**`B93934206`**``
serialized to `` `**B93934206**` ``, turning bold text into literal
asterisks.
ProseMirror ranks a text node's marks by schema order, which Tiptap
derives from extension priority, so the parser's correct order was
renormalized. Raise code above emphasis; link stays below code so
linked code labels keep serializing.
The upstream tokenizer matched `$([^$]+)$` with no delimiter rule, so a
second dollar sign anywhere in the paragraph turned prose into a math
span: `Costs are US$ 5,000 and R$ 40,000` lost the space after `US$`.
Require a non-space next to each delimiter and forbid a newline inside,
matching the common dialect. Real math still parses.
A file saved by an earlier Orca version carries class="orca-details"
in its markdown source. The prior commit stopped the serializer from
ever writing that class, which also stopped it from preserving one a
source already had, so re-saving such a file dropped the class and
the round-trip eligibility check then failed to recognize the file as
its own, regressing it back to Source mode. The details node now
carries a flag set only when its source opening tag had the class, and
the serializer re-emits the class only when that flag is set.
The markdown serializer always injected class="orca-details" into
saved <details> tags. The rich-mode round-trip check compares the
serialized output against the source's literal opening tag, so any
user-authored <details> without that class failed the comparison and
fell back to Source mode, making the details extension unreachable
from a file. The class is already applied to the rendered DOM node
independently, so the serializer no longer needs to write it into the
markdown source.
The nested (?:[ >]*(...)?)* quantifier let a long run of leading
spaces or > with no closing [ trigger catastrophic backtracking,
freezing the renderer on any document with such a line. Replace it
with a single non-nested character class, which is linear and safe
to over-admit since the parser confirms every candidate.
hasLinkReferenceDefinition ran a full remark parse on every content
change with no size guard, unlike the HTML round-trip check beside it.
Above the same 50,000-char cap, the pre-filter match is now trusted as
a definition, keeping rich mode blocked rather than risking an
unparsed document opening in it.
The pre-filter only matched one list-or-blockquote transition, so a
definition under e.g. list-then-blockquote or three-level nesting
skipped the parser confirmation and rich mode stayed on for content it
cannot round-trip.
