Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG
Environment:

• VSCode Version: 1.17.2
• VsCodeVim Version: 0.10.2
• OS: OS X El Capitan 10.11.6

What happened:

Start typing a closing tag and let Auto Close Tag trigger drop down of autocompletions. Eg, Type

<v-dialog></...

The options will show in a drop down but then VSCode becomes immediately unresponsive. I bring up Mac's Activity Monitor and see "Code Helper" at 99% CPU. Force quitting Code Helper alleviates the issue but it will happen each time you reproduce the steps.

Auto Close Tag works fine withVSCodeVim plugin disabled.

What did you expect to happen:
Using VSCodeVim and Auto Close Tag plugin to work together without crashing VSCode.

How to reproduce it:
Install VSCodeVim and Auto Close Tag plugins. Open an HTML file and type any HTML tag and then start typing its corresponding closing tag. Let autocomplete options show and observe activity monitor for CPU usage.

Start by installing VSCodeVim and Auto Close Tag in VS Code, opening an HTML file, and reproducing the closing-tag autocomplete case while watching Activity Monitor. Compare the behavior with VSCodeVim disabled; done means both extensions can be enabled without Code Helper becoming unresponsive or reaching about 99% CPU.
