Given the context around this game, the sight of McInnes raising his arms in the visiting dugout after Rangers' late equaliser will be a sickener for Hearts fans.
However, they can be proud of a depleted side who were missing eight first-team players, plus another after a first-half injury to makeshift full-back Rogers Mato.
Amid a hectic schedule, Vrancken's men were relentless in their pursuit of a memorable fightback victory, inspired by Braga on his 27th birthday.
The Portuguese striker's decision-making was questionable at times - as was that of his team-mates - but his work-rate was infectious, showing bravery to turn in Malachi Fagan-Walcott's header back across goal after a wide free-kick.
His driving run into the left of the box, followed by a deflected attempt, then led to Miller smashing Hearts in front.
Better execution on the counter would have taken this game away from Rangers, adding to the pain Vrancken and his players will feel, but that will all be forgotten if they can dispatch bitter rivals Hibernian in Sunday's League Cup semi-final.
