The bug
In 1.12.2, common prefixes were automatically tab-completed. This allowed people to easily narrow down the result set. As of 17w50a, this is no longer the case.
How to reproduce
Type
/scoreboard objectives add name mHit tab
You will be given a huge list of tab-completion suggestions. Finding the one you need will be no faster than typing it. However, 1.12.2 Would first tab-complete to /scoreboard objectives add name minecraft. - from there, you could keep on specifying what you need, for example by adding a b at the end and hitting tab again, which would give you /scoreboard objectives add name minecraft.broken: and so on.

I'd like to add something I said in my bug report (that is a duplicate). So I'll copy-paste that here. Like I said there, I'm not sure this was something that existed, but even if it wasn't, I'm hoping the devs couls add that while they're at it, because it would be so useful ! (at least for IDs such as scoreboard criterias) So here it is :
" I can't remember if something like that was there in 1.12, but a useful thing would be to have additionnal suggestions that would always be at the top (except if there are results that would end before having a "non-letter character") but that would never suggest anything after the next "non-letter character".
Explanation :
Start with nothing written for the criteria → Every ID is suggested
Type "d". Let's imagine you have a mod called "Doors" → Suggestions will be "deathCount", then "dummy", THEN "doors" items
Delete that "d", you actually wanted to type "minecraft" → Suggestions are "minecraft.", then all the full IDs starting by that
Add that dot → Suggestions are "minecraft.broken:", "minecraft.crafted:", "minecraft.custom:" etc (so we have a clear list of what is possible directly after "minecraft.", instead of having to scroll down for half a day or try every letter, and more than carefully since something like "crafted" and "custom" happens), and then we have all the full IDs starting by that
Tpye "c" → Suggestions are "minecraft.crafted:" and "minecraft.custom:", then all the full IDs starting by that (as usual)
► So, in short, nothing changes at all about which full IDs are shown, we only add what are all the categories in which they are scattered. "
Confirmed in 18w05a.
