typescript: Memory usage of nuxt dev with typescript grows indefinitely

Describe the bug The memory usage of nuxt with typescript enabled seems to grow unbounded with each reload of nuxt.config.js

To Reproduce Steps to reproduce the behavior:

1. Create a project using yarn create nuxt-app myproject. Choose typescript for the programming language and use default for all other options.
2. Run yarn dev
3. Open nuxt.config.js in your editor and just save it to trigger a nuxt build.
4. Repeat 3. a couple times.
5. Memory usage as reported by nuxt grows indefinitely

Expected behavior Memory usage should stay below ~500MB

With lang=ts, if I run node --trace-warnings node_modules/.bin/nuxt >/dev/null, I get a stack trace:
