Thanks, good catch, but you modified a generated doc:

<!-- DO NOT REMOVE the following comments -->
<!-- GENERATED props -->
### General
<div class="props">
<PropGroup label="General">
<PropBlock type="BOOLEAN" name="icon" label="Icon">
<PropBlock type="TEXT" name="icon" label="Icon">
...

You want to modify https://github.com/openhab/openhab-webui/blob/main/bundles/org.openhab.ui/web/src/assets/definitions/widgets/system/icon.js instead first (pb to pt), then regenerate the docs with the script described in
https://github.com/openhab/openhab-webui/blob/main/bundles/org.openhab.ui/CONTRIBUTING.md#documentation--resources

Ughh, it seems that those changes shouldn't be there. I've removed them, so that this PR only contains changes to icon
