Need to clear cache and restart parcel on many save

bug report

This is the same issue mentioned in #9729

Changes aren't getting picked up after the first save. I need to constantly clear the cache and rerun parcel. Even with reloading and hard reloading nothing changes. I can see parcel doing some work building something but changes are not reflected in the browser unless I clear the cache and rerun parcel.

Configuration (.babelrc, package.json, cli command)

I just run yarn start which runs parcel

Expected Behavior

Rebuild on every save and at least by refreshing the browser I get the latest code.

Current Behavior

After one or two saves the page in the browser remains the same literally nothing changes. Parcel is building something in the terminal but it is not reflected in the browser even if I refresh.

Possible Solution

n/a

Context

I haven't been using Parcel for long (a month?), but I think it has already happened quite often.

Code Sample

It's a Vue SPA, nothing fancy. This happens even on big changes such as creation and use of new components.
