As a redstoner myself I can also confirm this has happened to me on some rare occasions on my redstone world. I’m on 1.2.16 on iPad Pro.

I should note, this also happens on windows 10. It would be nice if we could select multiple affected platforms on the bug report🙂

Included the affected platforms in the ticket description.

This bug is not fixed as of the latest bedrock update, contrary to the changelog.

Which blocks are you getting mobs spawning on specifically?

[Mojang] Mega_Spud (Jay) 2018-07-24T13:38:10Z

Using 1.5.1.2, I tested a flat world with a 180x180 walled off area, and I placed the following blocks within that area.

In Java (1.13) and Bedrock (1.5.2 and 1.6) mobs did not spawn on:

Redstone Dust
Redstone Torch
Comparator
Repeater
Rails
Hopper
Piston

Time was set to night, difficulty to Hard, and mob spawning was enabled. No mobs were seen to spawn on the components.

Please bear in mind that mob spawning is not disabled on all redstone components on the Java edition either. For example, mobs will continue to spawn on:

Dispenser/Dropper
RS Lamp
Observer

thanks for being active on this issue! It appears I may have been given some wrong reports about things spawning on redstone. I had multiple people tell me that it was not fixed. So I reopened the bug report.

I am currently away from my pc, but when I return I will also conduct some tests to confirm that things do not spawn on RS components🙂

[Mojang] Mega_Spud (Jay) 2018-07-27T07:38:08Z

Ok thanks. If there is broken behaviour I'm happy to reopen the bug for a fix.
