Hot Module Reload takes almost 2 minutes!

[baermathias]

Environment
tns info --> √ Component nativescript has 6.5.0 version and is up to date.

Describe the bug
I changed the button color and saved the file at 13:37:35.187 (start time) and the whole process ended almost two minutes later at 13:39:11.787 (end time)

To Reproduce
Create a nativescript-vue project with the CLI and at least two single file components. Then make some changes and save them.

Expected behavior
Display changes immediately like Vue.js for Web

Additional context
I am using Sidekick and Android Emulator with Galaxy_Nexus_API_29:5554

Here is the complete Sidekick console output, after a change is detected:

@baermathias while using local CLI build via this test app I am unable to reproduce the issue. It could be an issue related to Sidekick and if that is the case report the issue here

With tns preview on my physical smartphone it works well. But with Sidekick + Emulator it takes years. Could you move this issue to Sidekick?
