v1.0.11

The problem was that I over-optimized the
updated() method. I tried to only update
the height when _config changed, but
_config is not a reactive property - it's
set via the setConfig() method, not through
property binding.

What happened:

1. Working version: Height was set on every
   updated() call
2. Broken version: Height was only set when
   _config changed, but _config doesn't
   trigger changedProperties
3. Fixed version: Restored height setting
   on every update while keeping DOM caching
   optimization

The fix:

• Restored the height setting to run on
  every updated() call
• Kept the beneficial optimizations (DOM
  reference caching, event handler
  extraction, memory management)
• Added fallback to query the wrapper if
  cached reference isn't available yet

The card should now work correctly both in
preview and after saving the configuration,
while still benefiting from the
performance improvements for memory
management and caching.
