mtlcl410andClaude Opus 5.5 68dff686fe M6: a named kid is named up its own /Parent chain, and a radio option of any same-named field is chosen by the name (form.field-list) ...

A field's fully qualified name is built from the partial names of the field
and its ancestors, and a child names its parent with /Parent (ISO 32000-2
§12.7.4.2, Table 226). A /Kids entry with /T whose /Parent does not name the
field listing it is now named up its own /Parent chain, in the form reader
and in document inspection, as PDFium and MuPDF name it: pdf.js's
issue15096.pdf lists its two radio fields as Group1, not Group1.Group1.

Fields with the same fully qualified name are one field (§12.7.4.2), so a
radio option that a later one of them draws is now chosen by the name: it is
written through the first field that draws it and the others turn off.
Before, only the first field's options were accepted.
