What/why changed

  • фикс залипания ховера на touch устройствах

Summary by CodeRabbit

  • Bug Fixes
    • Improved hover behavior across buttons, fields, tabs, links, switches, and other controls.
    • Hover styles now apply only on devices that support precise pointer hovering, preventing hover states from sticking after touch interactions.
    • Preserved existing hover colors, backgrounds, focus states, and transitions while making their behavior more consistent.
  • Style
    • Updated styling validation to avoid false positives in mixin-based CSS.

📝 Walkthrough

Walkthrough

The pull request adds a shared applyHover mixin that applies hover styles only for hover-capable fine-pointer devices. Component styles now use the mixin for existing hover rules. Stylelint disables a rule that reports false positives for mixin interpolations.

Changes

Hover behavior standardization

Layer / File(s) Summary
Define and export applyHover
.stylelintrc.js, packages/plasma-new-hope/src/mixins/*
The new mixin wraps styles in @media (hover: hover) and (pointer: fine). The mixin is exported, and the related Stylelint rule is disabled.
Migrate button and form hover styles
packages/plasma-new-hope/src/components/Button/..., Chip/..., CodeField/..., CodeInput/..., Dropzone/..., Link/..., LinkButton/..., _beta/EmbeddedButton/...
Existing hover rules now use applyHover. Shared hover declarations remain unchanged.
Migrate selection-control hover styles
packages/plasma-new-hope/src/components/Segment/..., Switch/..., Tabs/...
Segment, switch, and tab hover rules now use applyHover, including selected-state and divider styles.
Migrate text-input hover styles
packages/plasma-new-hope/src/components/TextArea/..., packages/plasma-new-hope/src/components/TextField/...
Text area and text field hover rules now use applyHover. Existing exclusions and token assignments remain unchanged.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c1d28

Hover states are now suppressed on touch-primary hybrid devices even when a mouse is connected. This is a bounded UI-behavior risk across migrated components until the intended hybrid-input behavior is defined.

12-12: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Define hybrid-device behavior for applyHover.

(hover: hover) and (pointer: fine) evaluates the primary input only. A touch-primary hybrid with a connected mouse therefore omits the hover styles. A mouse-primary hybrid can apply them while touch input is available. If hover styles must support any connected mouse, use any-hover and any-pointer; otherwise document and test the primary-device behavior.
