fix(fn): consistent highlights of tags across zoom levels [ci visual]

[darksmo]

Description

On some operating systems supporting sub-pixel rendering the browser may inconsistently approximate the height/widths of boxes across zoom level. The issue becomes apparent when multiple controls are placed together (e.g., table rows, tags, input boxes) as the user zooms in/out.

Specifying the border-width property is a solution that does not involve
using future CSS specs or GPU-based calculations.

Screenshots

This issue occurs across different zoom levels.

Please check whether the PR fulfills the following requirements

1. The output matches the design specs

• All values are in rem
• Text elements follow the truncation rules

• active state of the element follow design spec
• selected state of the element follow design spec
• selected hover state of the element follow design spec
• pressed state of the element follow design spec
• Responsiveness rules - the component has modifier classes for all breakpoints
• Includes Compact/Cosy/Tablet design
• RTL support

2. The code follows fundamental-styles code standards and style

• only one top level fd-* class is used in the file
• BEM naming convention is used
• Mixins are used for repeatable code (fd-rtl, fd-ellipsis, fd-flex, fd-selected, fd-focus, ect.)
• A11y support - keyboard support, screenreader support, proper ARIA attributes, etc.
• fd-reset() mixin is applied to all elements
• Variables are used, if some value is used more than twice.
• Checked if current components can be reused, instead of having new code.

3. Testing

• [na] tested Storybook examples with "CSS Resources" normalize option
• [na] tested Storybook examples with "CSS Resources" unnormalize option
• [na] Verified all styles in IE11
• [na] Updated tests
• last commit message should have [ci visual] so it can trigger chromatic visual regression (e.g. test: run chromatic visual regression [ci visual])

4. Documentation

• [na] Storybook documentation has been created/updated
• [na] Breaking Changes wiki has been updated in case of breaking changes.
