Issue number: resolves #28351 --------- <!-- 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. --> The collapsible large title transition does not support Dynamic Font Scaling as the position values are all hardcoded. Additionally, I noticed that the title and the text do not align very well even at the default font scale. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> I made a few changes to support Dynamic Font Scaling, fix the default scale alignment, and generally make this code easier to maintain (or at least I hope it will): 1. Removed most hardcoded values in favor of bounding box calculations. The hardcoded values that remain have comments explaining what they are. 2. Modified the back button animation so the container handles the translation and have the back button text animation handle its scale. Having the back button text handle the translation and the scale at the same time made it hard to figure out what the correct values should be. 3. Added a lot of comments explaining what we are doing/why **When the Large Title and Back Button Texts Do Not Match** | `FW-4146` (default) | branch (default) | `FW-4146` (scaled) | branch (scale) | | - | - | - | - | | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/a6261499-c5ca-4ee3-af62-fa124718ca46"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/0648c0b1-e1f8-43c1-9e7e-91489cc8ec4a"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/0def6d88-22d0-48b9-98b3-0ed2bbb407aa"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/3650ceb1-f4cb-4530-b7c6-17194f4ccd66"></video> | **When the Large Title and Back Button Texts Do Match** | `FW-4146` (default) | branch (default) | `FW-4146` (scaled) | branch (scale) | | - | - | - | - | | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/2b8035a4-81aa-4901-99e1-fd49db1fd0d7"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/e3c66978-2015-484e-b337-73ac1c4c02a1"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/437483a8-2495-4c54-9c27-47c91af4c562"></video> | <video src="https://github.com/ionic-team/ionic-framework/assets/2721089/05ef08b0-cf0d-469d-8834-533071a8c583"></video> | ## Does this introduce a breaking change? - [ ] Yes - [x] No <!-- If this introduces a breaking change, please describe the impact and migration path for existing applications below. --> ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. --> Note that the alignment of the title/button will not exactly match native iOS. The goal of this PR is to get something that is pretty close (similar to how it was when we originally implemented this) --------- Co-authored-by: Amanda Johnston <90629384+amandaejohnston@users.noreply.github.com>
