SID-01905: Unexpected URL params from form

We have some CSS magic that we are using to hide or show the left bar in our TWiki pages. (Yes, we could use JavaScript; I'm not a JS expert; CSS is working; thanks).

It works.

My question is, why am I getting two extra URL params that I'm not (explicitly) sending? I've used HTML forms in other laces in FW and this is the first time I've seen unexpected URL params.

The code (http://cfcl.com/twiki/bin/view/TWiki/WebTopBar):

<table border="0" cellpadding="0" cellspacing="0" style="width:100%" summary="">
<tr><td valign="top"><form name="hideshow" action="%SCRIPTURLPATH{"view"}%/%INCLUDINGWEB%/%INCLUDINGTOPIC%" method="get">
&nbsp;
<input type="image" src="%PUBURL%/%USERSWEB%/DocumentGraphics/%IF{ "$leftbar~'*Hide*'" then="showleftbar.png" else="hideleftbar.png" }%" title="%IF{ "$leftbar~'*Hide*'" then="Show Left Bar" else="Hide Left Bar" }%" name="leftbar" value="%IF{ "$leftbar~'*Hide*'" then="Show" else="Hide" }%" />
</form></td><td valign="middle"> <a href="%WEBLOGOURL%"><img src="%WEBLOGOIMG%" border="0" alt="%WEBLOGOALT%" style="border:none;" /></a></td>
<td align="right" valign="top" class="patternMetaMenu">
%IF{ "$leftbar~'*Hide*'" then="<link rel='stylesheet' type='text/css' href='%PUBURL%/Help/HideWebLeftBar/noleftbar.css'>" else="<link rel='stylesheet' type='text/css' href='%PUBURL%/Help/ShowWebLeftBar/showleftbar.css'>" }%
<noautolink>%INCLUDE{"%IF{"context can_login" then="%SYSTEMWEB%.WebTopBarLogin" else="<nop>"}%" warn="off"}%
</noautolink></td></tr></table>

The URL line that I see:

http://cfcl.com/twiki/...Web/Topic?leftbar.x=28&leftbar.y=8&leftbar=Hide

I don't understand why I'm getting leftbar.x and leftbar.y.

Discussion and Answer

The input type="image" sends x and y coordinates. This is HTML spec.
