As a workaround, The proper code should use v-else-if

Thank you for proposal!
By the way, people could mistake using v-if more than once instead of using v-else-if.

No, I want to actually use slot using shorthand. :)
It does not need to name id

@posva
I think this is kind of bugs, because normal programming languages support if statement like else if.
e.g.

if a == 1
  process for a
end
if b == 1
 process for b
end

is the same as

if a == 1; process for a
else if b === 1; process for b

Though I'm not a newbie in CS, but newbies can do with multiple if statement.

Is there any optimization to this?
Because it seems to me the same

[KSH-code]

@mingtianshi It may be applied in 2.6.15, because of plan from #11857.

I close this Issue, because it is not maintained

It is reproducible now.
