Slider resize is incorrect if the fonts are slow to load

[richardgaunt]

Summary

Slider calculates the height based on the highest slide in a set. But if a page loads, the slider resizes and then the fonts load the slide height calculation can be incorrect.

Add a listener to fonts load and adjust slider height when this fires.

Steps to reproduce

1. Slow the loading of fonts
2. Create a slider
3. Note the height issue

Observed outcome

Slider height is calculated incorrectly

Expected outcome

Slider height is calculated correctly

Test Env: DEV
Test Status: PASS
Test Result: Verified that the slider correctly calculates and maintains its height even when fonts load slowly. Simulated a slow font load by blocking the font request in the Network tab and observed whether the slider resized unexpectedly. Confirmed that the sliders height remains stable upon page load and after unblocking the font.

Normal slider height:
