Description

Issue

Sidebar avatar tooltips were not updating when characters were deleted, showing outdated names from previously selected characters.

Changes

Added update method to both tooltip and tooltipRight directives in src/ts/gui/tooltip.ts to dynamically update tooltip content when the tip parameter changes.

Technical Details

• Implemented Svelte action update lifecycle method
• Calls instance.setContent() to update Tippy.js tooltip content
• Existing usages with static values are unaffected since update is only called when parameters change

Implementation

The update method is now called automatically by Svelte whenever the tip parameter changes, ensuring tooltips always display current information for dynamically updating components like SidebarAvatar.
