Memory exhausted error coming while creating catalogrule with category

Question

I have around 50 categories. When I save the catalogrule without selecting the categories it gets saved correctly. But when I save along with selecting the category it display memory exhausted error. The exhausted error coming after 65 queries at the point when implode function is executed in Profiler.

If I set the category in already created catalogrule, it works fine.

What is the behaviour of Magento2

It seems like an issue with Magento of slow saving catalog rule.
