Why Prince of Wales shadowed rather than chased Bismarck

Why did Prince of Wales not continue pursuing Bismarck after the Denmark Strait action?

Her technical problems made another immediate fight risky, so she tried to keep Bismarck within radar range and maintain contact instead.

The decision follows from Prince of Wales's condition after the Denmark Strait action. The battleship was experiencing enough technical trouble to make another immediate engagement risky. Her force nevertheless tried to remain within radar range and continue monitoring Bismarck. Shadowing an enemy in this condition did not mean abandoning the operation.
