Description:
------------
strip_tags() removes long param tags even when param is in the exclude
list.

Reproduce code:
---------------
$var = "<param
value=\"file=http://www.whitehouse.gov/videos/2010/January/011910_FallsChurchVA.m4v&path_to_plugins=http://www.whitehouse.gov/sites/default/modules/wh_multimedia/wh_jwplayer/plugins&path_to_player=http://www.whitehouse.gov/sites/all/modules/swftools/shared/flash_media_player&skin=http://www.whitehouse.gov/sites/all/modules/swftools/shared/flash_media_player/skins/EOP_skin.swf&captions_url=http://www.whitehouse.gov/sites/default/files/av_closedcaption/011910_Race_to_the_Top_for_Education_Reform.srtI=http://www.whitehouse.gov/sites/default/files/audio-video/video_thumbnail/P011910LJ-0100-3_0.jpg&controlbar=bottom&frontcolor=AAAAAA&plugins=http://www.whitehouse.gov/sites/default/modules/wh_multimedia/wh_jwplayer/plugins/privacy/privacy,http://www.whitehouse.gov/sites/default/modules/wh_multimedia/wh_jwplayer/plugins/hat/hat,http://www.whitehouse.gov/sites/default/modules/wh_multimedia/wh_jwplayer/plugins/share/share,http://www.whitehouse.gov/sites/default/modules/wh_multimedia/!
 
wh_jwplayer/plugins/captions/captions&captions.file=http://www.whitehouse.gov/sites/default/files/av_closedcaption/011910_Race_to_the_Top_for_Education_Reform.srt\";
name=\"flashvars\" />";

$var = strip_tags($var, "<param>");



Expected result:
----------------
$var should be unchanged.

Actual result:
--------------
$var is empty.
