~~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.

@andacistan 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 https://github.com/vuejs/vue/pull/11857.
