+Remove backwards-compatible kebab-case transform for camelCase CSS variable names passed to the `style` attribute. If you were relying on the kebab-case transform in your styles, make sure to use the camelCase version to prevent missing styles. For example:
+
+```astro
+---
+const myValue = "red"
+---
+
+<!-- input -->
+<div style={{ "--myValue": myValue }}></div>
+
+<!-- output (before) -->
+<div style="--my-value:var(--myValue);--myValue:red"></div>
+
+<!-- output (after) -->
+<div style="--myValue:red"></div>
+```
+
+```diff
+<style>
+  div {
+-   color: var(--my-value);
++   color: var(--myValue);
+  }
+</style>
+```
