[Bug Report][3.7.0] Mount order of components of a VLayout inconsistent

[Joebayld]

Environment

Vuetify Version: 3.7.0
Last working version: 3.6.15
Vue Version: 3.5.4
Browsers: Chrome 128.0.0.0
OS: Mac OS 10.15.7

Steps to reproduce

• Open the link and view the console
• Toggle Vuetify versions between 3.6.15 and 3.7.0 while observing console

Expected Behavior

The mount order used to go from parent down to child, so the console would read:

Mounted Layout
Mounted Child

Actual Behavior

Since version 3.7.0, the mount order is from child up to parent. The console reads:

Mounted Child
Mounted Layout

Other comments

I'm pretty sure this is related to #15229

The behavior obviously is different between the versions and this actually broke a feature of my app. I was relying on properties being set in the parent's onMounted call before the children get mounted. I can make either option work, but I'm not sure what is expected behavior in the lifecycle chain.

This is back to how it worked in 3.5, #15229 was reverted in 3.7 because suspense is still unstable and broken.

I'm not sure what is expected behavior in the lifecycle chain

child -> parent for synchronous components, parent -> child for async:
