// TagPanel displays the most recent data for a single tag (e.g. [WDG]).
// Key=value pairs are shown in a table that updates in-place.
// If a value contains ';', it is treated as a LIST: the key is shown once
// and each list element gets its own row below it (key cell left empty
// for the continuation rows, like a merged-cell look).
// Example:  Devs=trackdisk.device;input.device
//   Devs   trackdisk.device
//          input.device
