What is the current behavior?

• When the document direction is dynamically changed, the menu does not switch to the correct position. For example, <ion-menu side='start'> will always be on the left side regardless of direction.
• When the side property is dynamically changed, the animation starts in the middle of the screen instead of off screen.

Issue URL: resolves #25601 #19489

What is the new behavior?

• Animation is smooth regardless of side property or document direction being dynamically change.
• Menu appears on the correct side based on document direction when dynamically updated.

Does this introduce a breaking change?

• Yes
• No

The newly added test is failing because it includes new screenshot checks. Make sure you run the Update Reference Screenshots job for this branch 👀 (I often like to leave my PRs in draft until all tests are passing, so it's more clear that it's actually ready for review.)

@amandaejohnston I've updated the references and the PR is ready to go.

This looks great! Just had a small request on the tests.
