Issue number: N/A --------- <!-- Please do not submit updates to dependencies unless it fixes an issue. --> <!-- Please try to limit your pull request to one type (bugfix, feature, etc). Submit multiple pull requests if needed. --> ## What is the current behavior? <!-- Please describe the current behavior that you are modifying. --> While working on the migration for the spinner to Ionic Modular, I noticed that we had a [Transform test page](https://github.com/ionic-team/ionic-framework/blob/2b5b9137fc164c2f3305e493510a884c0afbfcf0/core/src/components/spinner/test/transform/index.html#L5) without any context of why it was there. I found out that it's meant for a [bug](#19247) that was reported in v4 and we did have a [test](https://github.com/ionic-team/ionic-framework/pull/24643/changes#diff-7b7ff84d3845fbde015775aa2da960310e80f79ec01b1f4a5957d751eddce7c9R1) for it at some point but it was removed at a later date because it was [discovered](#25259) that it wasn't doing anything. So we don't have any coverage of it if there's a regression. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - Added a test to prevent a regression ## Does this introduce a breaking change? - [ ] Yes - [x] No <!-- If this introduces a breaking change: 1. Describe the impact and migration path for existing applications below. 2. Update the BREAKING.md file with the breaking change. 3.

What is the current behavior?
While working on the migration for the spinner to Ionic Modular, I noticed that we had a Transform test page without any context of why it was there. I found out that it's meant for a bug that was reported in v4 and we did have a test for it at some point but it was removed at a later date because it was discovered that it wasn't doing anything.
So we don't have any coverage of it if there's a regression.
What is the new behavior?
Does this introduce a breaking change?
