Latest Blocksy update breaks Stackable buttons

Hello,

After updating Blocksy to the latest version (update applied last Saturday), all buttons created with the Stackable block plugin display with a normal width but a collapsed/very small height on the frontend, even though they render correctly in the WordPress editor (backend).

I inspected the frontend CSS and found that the theme sets this variable globally:

--theme-button-line-height: 0;

This appears to be inherited by Stackable's button text, causing the line-height to collapse to 0 and the button to visually shrink in height while the width stays normal.

Troubleshooting steps I've already taken:

- Cleared all caches (page cache, browser cache, tested with cache-busting parameters) — issue persists.

- Disabled Stackable's CSS optimization option — no change.

- Checked the Blocksy Customizer button settings — I could not find a line-height option that affects this, and changing other button settings had no effect on the issue.

- Switched to the Twenty Twenty-One theme with Stackable still active — the buttons display correctly, confirming the issue is theme-related, not a Stackable bug.

- Rolled back Blocksy to the previous version — the issue is immediately resolved.

This strongly suggests a regression introduced in the latest Blocksy release affecting the --theme-button-line-height custom property, which negatively impacts buttons built with the Stackable plugin.

Could you please look into this and let me know if a fix is planned, or if there's a recommended workaround in the meantime?

Thank you, Catherine
