how to set focus on editor component

[dantrevino]

Version

@toast-ui/vue-editor": "^1.0.4

Test Environment

Chromium Version 74.0.3729.169 (Official Build) Built on Ubuntu , running on Ubuntu 19.04 (64-bit)
Google Chrome Version 74.0.3729.157 (Official Build) (64-bit)

Current Behavior

Set focus does not work. None of the below options work, including the TUI Editor API

mounted () {
    this.$refs.editor.focus()
    this.$nextTick(function() {
      this.$refs.editor.focus()
    })
    this.$refs.editor.invoke('focus')
}

Expected Behavior

Upon render cursor should be set to the contenteditable div

<div contenteditable="true" class="tui-editor-contents tui-editor-contents-placeholder" data-placeholder="Start writing here..."><div>

Same as issue nhn/tui.editor#314 which was closed with no resolution.

@dantrevino Sorry for late reply. I try to reproduce this issue but focus works well in mounted function. Is set ref as editor in your editor?
