The cell padding was a constant in three places that disagreed with each
other, so a narrow column lost 0.38cm it did not have: a bibliography
marker column of 0.71cm wrapped "[2] " onto three lines and every entry
grew with it, costing a fixture a whole page.
The table now carries its own margins (w:tblCellMar, direct or from the
table style; fo:padding on the ODF cell style) and both exports write
them back. A side within a twentieth of a millimetre of the default is
the default, or Word's 108 twips would tag every table.
Its leader is real dots now, not a border, so it scales with the font and
reaches the PDF as text. Title and entries follow the document's Heading 1
and default style, which is what the index styles of Word and LO are based on.
Word's Title style tightens by -0.5pt, so a title came out ~3mm wide of
LibreOffice's. letterSpacingPt joins TextProps and rides both formats
(w:spacing, fo:letter-spacing).
Line spacing needed the same care: it is proportional to the font's natural
line height, so the factor and that height are now separate CSS variables and
editor.css multiplies them in one place. Before, whichever of the two was
declared nearer simply overwrote the other — a block carrying its own font
silently dropped the style's spacing.
A paragraph holding an image rendered a line taller than it does anywhere
else: under white-space: pre-wrap the browser already shows the last line, so
ProseMirror's hack BR adds an empty one. The hack is kept where it earns its
keep — after a real break it carries the caret onto the empty line, and in an
empty block it is the only line box there is.
The marker took only the weight of the item's first text portion. It now takes
the family, slant, size and color too — as custom properties on every item,
since they inherit and a nested item must not take its parent's.
A named paragraph style reaches it a second way: the marker inherits the list
item's own font, and the document stylesheet only styled the item's paragraph,
so an imported document whose Standard style is Arial drew its numbers in the
editor's serif default. styleCss now emits the style's text half for the item
too (li:has(> …)).
Both file formats carry marker formatting per level, so a level definition is
written only for a list whose items agree: ODF mints a character style the level
points at, DOCX the level's w:rPr. A mixed list gets none on purpose, so
LibreOffice keeps applying its own first-portion rule.
A bold mark sits inside the item's paragraph and never reaches ::marker, so the
roman numerals of a numbered heading stayed light while their text was bold.
A plugin tags such items and editor.css weights the marker. The trigger is the
first text portion, which is the rule LibreOffice numbering itself uses.
Lists were padded 1.5rem per level on screen while the DOCX and ODT
exports place item text at LIST_LEFT_STEP_CM (1.27cm) per level, so the
editor disagreed with its own output and with Word and LibreOffice by
6.4mm on the first level, doubling with each nesting level.
Cells padded 0.1cm on all sides; Word and LibreOffice use 0.19cm left and
right and none top or bottom. Text sat 0.7mm too far left and every row
was 2mm too tall, so the offset accumulated down a table.
odf-kit only writes the fo:padding shorthand, which ODF defines as a
single length — LibreOffice drops a two-value form — so the export
expands it per side.
