Are you sure about the fact that increased recovery rate for life does not multiply the max amount of life you get from leech per second? Eg. 50% increased life recovery rate resulting in 30% life per second recovered from leech, if you have the unmodified 20% cap?
Or am I misunderstanding you, and thats not what you are saying (I assume that "increasing recovery per second" refers to life/es recovery rate mods)?

Yes. The whole point of that stat is it's a maximum, increasing the value of the thing it's a maximum for doesn't increase the maximum.
It has worked this way since it was introduced, and the wiki page explains this interaction (see here). Your total (the wiki says combined) leech from all instances is modified by increased leech per second, then capped by the maxmimum.
EDIT: I misread your post as referring to the leech specific modifiers. Modifiers to generic recovery of life/mana/es are applied to the sum of all sources of recovery, including your total from leech, which is a capped value.
This is not actually raising the maximum stat, which is what confused me about your wording, but because the value, which has already had the maximum applied, is then combined with other sources of recovery, and a further modifier applied, the result (which is not just from leech, but from all sources) is not limited by that maximum.
Technically, those shouldn't be applied separately (and should not be multiplicative with the more specific versions), but in the previous system there were technical reasons they could not be applied together. Now that limitation is removed, but we do not want to change the function of those stats until a patch when we will have time to correctly adjust the relevant balance values to account for the change, as it would have a significant effect. This is tentatively scheduled for a medium-term future patch.
