Debug active TU source (similar to debug active file, but check which source file is associated with active header)

Issue Type: Feature Request

Situation :

You are debugging a header, with a testfile. You set breakpoints in the header and trigger a debug on testfile. Now currently, when you restart debugging, it picks the current header you are viewing and attempts to start compiling and debugging it, but it can't because its a header that doesn't have a main.

Request :
The restart option remembers from which file the debugger was triggered, so we don't have to re-navigate to the file manually and then trigger the debugger from there.

Nell’issue non sono indicati file, test o punti di ingresso. Inizia tracciando il flusso di debugging dopo un riavvio e il modo in cui l’header attivo viene associato al file sorgente che ha avviato il debugging; il lavoro è completato quando il riavvio da un header usa il file sorgente associato invece di tentare di compilare l’header.
