When I select a heading 2 anchor in the menu, the browser tab freezes (Chrome), and I have to close it. I.e. the "Hey there" and "Tell me more" in the image below.

It's easily reproducible. Initialize a clean project, something like this:
mkdir docz-test
cd docz-test
npm init -y
npm i -D docz@next docz-theme-default@next
touch hello.mdx
Fill hello.mdx with this:
name: Hello
menu: Intro
---
# Welcome
How are you doing?
## Hey there
We can talk.
## Tell me more
Contact us for more talking.
Run node_modules/.bin/docz dev, go to localhost:3000 and click one of the two links in the menu. Freeze! 馃崸
I am using these versions:
"docz": "^1.0.0-rc.8",
"docz-theme-default": "^1.0.0-rc.8"
Environment
Thanks to warning me @draperunner, I seeing what's happening 馃
Fixed, I don't know why but was something related to React.Suspense. I was using the lazy method of @loadable/component with suspense, it works fine for routes and code splitting, but was crashing when some location has a hash, so awkward, I just change to the loadable method without suspense and now it's working.
Btw, will be released in the next version.
I'm running into this problem, too. Is there any schedule for next release?
v1.0 was just released and resolved this issue for me :+1:
