Heater wires of the tubes ECL82 and ECL86 do not connect

Description

Wires do not snap to the heater pins of the tubes ECL82 and ECL86. The symbol checker reports:

Off grid pin 4 ‘F1’ at location (-2.54 mm, 9.53 mm) in unit C. Off grid pin 5 ‘F2’ at location (2.54 mm, 9.53 mm) in unit C.

Steps to reproduce

1. Create a new project.
2. Place an ECL82 or ECL86 from the symbol library into the schematic.
3. Try to connect wires to the heater pins labeled F1 and F2 (Pins 4 and 5).
