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. --> If a dev wants to view a test page in dark mode, they have to manually add the styles. This can lead to a slowdown. Plus they can't use Playwright's `goto` to test both light and dark. In order to test dark mode with Playwright, the dev would need to use `setContent` instead of `goto`. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> Dark mode can be added to any page by appending `palette=dark` to the URL. - The param will be used to add a link tag with the correct palette file. - Playwright will load the correct palette file when a dev uses `goto` and `{ themes: ['dark'] }` ## 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. Add "BREAKING CHANGE: [...]" to the commit description when merging. See https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#footer for more information. --> ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. --> I recommend using badge to try this out. It already has a `goto` in the basic tests.
