Problem Description

Steps to reproduce
1. prepare a zul file that contains <style> tag, like .z-listcell.red .z-listcell-cnt, .z-label.red

<zk>
	<style>
		.z-listcell.red .z-listcell-cnt, .z-label.red{
			color:red;
		}
	</style>
	<window id="searchWin" title="Search Storage Item" border="normal" width="600px">
		A zul that contains style tag causes selectors problems.
		<vbox hflex="true">
			<hbox>
				Filter : 
				<textbox id="filterBox" value="*" /> 
				<button id="searchButton" label="Search" />
			</hbox>
		</vbox>
	</window>
</zk>

2. Searcher.find("#filterBox") return null
3. Until I remove <style> tag , Searcher can find components.

There is no such problem when using @Wire with SelectorComposer.

This issue only occurs when <style> is at beginning, no happen when we put <style> at the end of zul.

#id not work, but select by "tag" still works, e.g.:
Searcher.find("#filterBox") // null
Searcher.find("window") // correct
