Hitting the tab key inserts <tab></tab>

[AndreSteenveld]

Issue Type: Bug

I am not completly sure what the root cause is. But when I open a file and start typing everything works as you'd expect. After going to another window or to another file and coming back to the orginal one hitting the tab-key will insert <tab></tab>

I had this happen too

@AndreSteenveld @skbolton This is being caused by the vim extension: VSCodeVim/Vim#3096

Looks like a fix has already been checked in for it, not sure when the next release will be. In the meantime, the extension repo has the .vsix files of the previous releases, so you could downgrade to the previous version
