This commit adds a new `onpopuphidden` attribute to the `<panel>` element that defines the workspace panel. This attribute triggers the `ZenWorkspaces.handlePanelHidden()` function when the panel is hidden.
This change is necessary to allow the application to properly handle the case when the workspace panel is hidden so that the reorder mode can be disabled.
The following changes were made:
- Added the `onpopuphidden` attribute to the `<panel>` element in `zen-popupset.inc.xhtml`.
- Added a new CSS class `.zen-workspace-last-place-drop-target` to `zen-workspaces.css`.
- Modified the `zen-workspaces.css` file to display the `.zen-workspace-last-place-drop-target` class only in reorder mode.
- **Preferences**:
- Added a new preference `zen.view.sidebar-expanded.on-hover.paused-for-expand` to manage the paused state of the sidebar hover functionality.
- Updated `zen.view.sidebar-expanded.on-hover` preference handling to ensure proper behavior when toggling the sidebar.
- **ZenUIManager.mjs**:
- Updated `_updateOnHoverVerticalTabs` method to handle the expanded state and remove hover attributes when the sidebar is expanded.
- Refactored `_updateEvent` method to check and handle the expanded state of the sidebar, and to open or close the sidebar accordingly.
- Added `openSidebar` and `closeSidebar` methods to manage the sidebar's expanded state and related attributes.
- Refactored `toggleExpand` method to handle the new `paused-for-expand` preference and ensure proper toggling of the sidebar's expanded state.
- **zen-settings.js**:
- Updated `setCompactModeStyle` method to handle the new `paused-for-expand` preference.
- Ensured that the `paused-for-expand` preference is reset when the sidebar expand strategy is changed.
- **zen-browser.js**:
- Added the new preference `zen.view.sidebar-expanded.on-hover.paused-for-expand` with a default value of `false`.
- **Submodule Updates**:
- Updated `l10n` submodule to the latest commit `dd93803b84f398834049a3f650536fbdbd14cbca`.
- Updated `zen-components` submodule to the latest commit `d853fa8de4167dfd4d1289f4f15792a698c738c3-dirty`.
- **Miscellaneous**:
- Fixed indentation issues in `ZenUIManager.mjs`.
- Removed commented-out code in `ZenUIManager.mjs`.
- Ensured proper formatting and alignment of code blocks.
