User report: opening an .html file with a '../.archive/' hyperlink in
a new tab works (zddc-server intercepts and serves the right file),
but clicking the same link inside the file previewer does nothing.
Two combined causes:
1. The previewer's iframe was loaded from a blob: URL (built from
the file's bytes). Relative URLs in the iframe resolve relative
to the blob URL — '../.archive/X.html' becomes 'blob:.../.archive/
X.html', which is gibberish. The browser never sends a request to
the server, so the .archive interception never fires.
2. sandbox="" disables every iframe capability including popups,
so even <a target=_blank> is silently swallowed.
Fix per tool:
- archive (table.js): for HTML preview, use file.url (the real
server URL) directly when available; fall back to blob only for
File-System-Access-API mode where there's no server to intercept
anyway. Now relative links in archived HTMLs resolve against the
actual server origin and the .archive interception fires as
designed. Sandbox loosens to allow-same-origin + allow-popups +
allow-popups-to-escape-sandbox so resources within the iframe
load and link clicks (default target / target=_blank / middle-
click) work normally. allow-scripts is intentionally NOT set —
archived HTML still cannot run JS in the popup's origin.
- transmittal (files-preview.js) + classifier (preview.js): same
sandbox loosening for consistency. These tools' files are
typically local (FileSystemAccessAPI), so the file.url branch
doesn't apply — relative URLs that depend on a server still
won't resolve in local mode (intrinsic limitation, no server).
Tested behavior preserved:
- PDFs: unchanged (no sandbox, browser's PDF viewer handles).
- Images / docx / xlsx / tiff / zip / text: unchanged.
- HTML in zddc-server-backed archive: relative '../.archive/' links
now navigate the iframe to the correct target file.
