Preserve value in reload mode

[aliabid94]

We had a regression where values of compnents were not preserved in reload mode, so when you edited the source file, values would be reset to empty. This is fixed.

Previously, state was not preserved in reload mode either, a separate bug. Also fixed.

Fixes: #8855
Fixes: #8641

Nice @aliabid94! Is it possible to add a test for this? We have e2e tests that specifically test reload mode but we seem to still get lots of regressions around it...

[abidlabs]

Otherwise, works great nice fix!
