Global Link Hover Color overrides Block Level style for Query Navigation Next & Previous blocks

[jeflopodev]

Description

Given the code below, the blocks core/query-pagination-next core/query-pagination-previous should override the value of styles.elements.link.:hover.color.text set to #00ff00. Since these two blocks have block level definitions of that same style set to #ff0000 instead.

Other blocks with links like core/query-pagination-numbers & core/paragraph can override it, and work as expected (hovering with the color #ff0000 set). I've used them just to check.

home.html & theme.json

```html

Mauris convallis lectus sit amet aliquet bibendum

``` ```json { "styles": { "elements": { "link": { ":hover": { "color": { "text": "#00ff00" } } } }, "blocks": { "core/paragraph": { "elements": { "link": { ":hover": { "color": { "text": "#ff0000" } } } } }, "core/query-pagination-next": { "elements": { "link": { ":hover": { "color": { "text": "#ff0000" } } } } }, "core/query-pagination-previous": { "elements": { "link": { ":hover": { "color": { "text": "#ff0000" } } } } }, "core/query-pagination-numbers": { "elements": { "link": { ":hover": { "color": { "text": "#ff0000" } } } } } } }, "$schema": "https://schemas.wp.org/trunk/theme.json", "version": 2 } ```

Step-by-step reproduction instructions

1. Create enough posts to have pagination
2. Create a Posts page, and set it as the static Post page in Settings > Reading
3. Create a templates\home.html template with the core/query-navigation-next & core/query-navigation-previous blocks
4. Setup theme.json so it sets a color value for the properties styles.elements.link.:hover.color.text, styles.blocks.core/query-navigation-next.elements.link.hover.color.text & styles.blocks.core/query-navigation-previous.elements.link.hover.color.text
5. Navigate to the posts page and hover the next and previous links to check

These are the selectors used for every element while forcing :hover state in the DevTools:

Environment info

• I've tried this with WordPress 6.3.1 & 6.4-alpha-56597 + Gutenberg 16.6.0
• I've used a custom made theme named simple with the very minimal files needed to reproduce the bug. It's shown in the video.
• I've also tried this using the Twenty Twenty Three theme (and also happens there)
• I'm using Google Chrome 116.0.5845.188 (Build oficial) (64 bits) (cohort: Stable) in Windows 11 Version 21H2 (Build 22000.2416)

Yes

Please confirm that you have tested with all plugins deactivated except Gutenberg.

Oh wait. At first I thought the global style was being used over an existing and a more specific block level style. But now I think that this is because there's no block level hover color styles being used/applied for core/query-pagination-next and core/query-pagination-previous blocks.

That's why it falls back to the value from styles.elements.link.:hover.color.text

I've added a video of the CSS selectors being used.
