etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
There have been plenty of issues reported in regards to Vue components
failing to propagate events. It seems like when we updated the Vue
output target and started to use the provided runtime code from the
output target, we have changed the way how event names are computed.
Ionic has used a custom wrapper for handling events that would kebab
case event names. That is no longer needed and removing it fixes
observed issues.

Reproduction case working:
https://stackblitz.com/edit/vj18czas-wdhzxjom?file=package.json

## What is the new behavior?
We have received a fix for this in
stenciljs/output-targets#617 which I hope will
resolve this issue by updating the dependency.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
  2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
