HMR crash when changing from / to ng-template syntactic sugar syntax #63361
Description
Which @angular/* package(s) are the source of the bug?
core, compiler
Is this a regression?
No
Description
As far as i know
<div *directiveXYZ></div>
is just syntactic sugar to
<ng-template directiveXYZ>
<div></div>
</ng-template>
However, when i do changes between those 2 forms, i am getting HMR error.
Please provide a link to a minimal reproduction of the bug
