Same track channel skips repeater, causing redstone signal decay

[ViRb3]

In general, when the code tries to connect two tracks, the channel will be at least 3 blocks wide, and a repeater will be placed in the middle to extend the redstone signal. However, there appears to be a case when the code tries to connect the same track to itself, which results in a 1-width block and no repeater. This can cause the redstone signal to decay and not reach further down the circuit.
