Bug report

After the client and server are compiled successfully, during the "Rendering static HTML" phase, the rendering of pages gets slower and slower until a crash:

Steps to reproduce

Check out the repo below. Yarn install. vuepress build docs.

https://github.com/jaunt/vuepress-vuetify2

What is expected?

The speed of each page rendering should be constant (they are duplicated md files). Memory should not run out.

What is actually happening?

Rendering gets slower and slower until javascript runs out of heap memory:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
