When a form template `tag-chooser` field is populated from a tag group, each `<o…ption>` is rendered with its display value (the tag name upper-cased, or its description). Selecting an option then has to translate that display value back to the underlying tag name before storing it on the composer. `handleSelectedValues` did this translation by lower-casing the option value (`"HIGH"` -> `"high"`) and `handleInput` matched the result case-sensitively against the real tag names. On sites with `force_lowercase_tags` disabled, tag names keep their casing (e.g. `"High"`), so the reconstructed `"high"` never matched, the selection was silently dropped, and the dropdown reset to its placeholder. Lower-case tag names round-tripped fine, which is why this only affected sites allowing mixed-case tags. This regressed in ed8a62e2729, which switched the option value from the tag name to the upper-cased display and reintroduced the lower-casing round-trip to reverse it. Instead of guessing the casing, build a map of each choice's display value back to its exact tag name and look the selected option up in it. Selections are now preserved regardless of tag name casing. Adds a system spec covering tag names with uppercase characters and `force_lowercase_tags` disabled.
