Export to Blu-ray sup: inline <font face> tag is ignored per line (only the global font is used)

[Victory61]

Description

When exporting to Blu-ray sup (image-based export), the inline <font face="...">
attribute set in the main editor is not applied. Every line is rendered with the single
global Font name chosen in the export dialog.

By contrast, the inline <font color="..."> attribute from the same tag IS honored
per line. So the two attributes of one <font> tag are treated inconsistently: color is
applied per line, typeface is not.

The result is that it's impossible to mix typefaces in a single .sup that reflects the
source formatting — the font must be re-selected manually for each group of lines in the
export dialog, even though it was already defined in the edit view.

Steps to reproduce

1. Create/open an SRT with lines using different inline fonts, e.g.:
   • <font color="#B6AA5C" face="Papyrus">Line A</font>
   • <font color="#9B9B9B" face="Tahoma">Line B</font>
2. File → Export → Blu-ray sup...
3. Look at the preview / exported images.

Expected behavior

Each line is rendered with the typeface declared in its own <font face="..."> tag,
matching what the main editor shows. The global Font name acts only as the
default/fallback for lines that have no face attribute — i.e. consistent with how
color is already handled per line.

Actual behavior

All lines are rendered with the global Font name from the export dialog. The per-line
face= value is ignored (a line tagged face="Papyrus" is rendered in Tahoma). The
color= from the same tag is applied correctly, which is inconsistent.

Workaround

Manually select the relevant lines in the export list and set the font for each group
before exporting.

Environment

• Subtitle Edit 5.1.0
• Windows 11

Screenshots attached: edit view (with face="Papyrus") vs. export preview (rendered in
Tahoma).

Thanks for the clear report - confirmed, and it is a regression from SE4. The renderer only read the color attribute of a <font> tag; face and size were dropped.

Fixed in #14477: <font face="..."> and <font size="..."> are now honored per segment in all image-based exports (Blu-ray sup, VobSub, BDN-XML, ...). The dialog font is only the default for text outside such a tag, the same way color already worked. Will be in the next release.
