External Legend Graphic reported size incorrect in WMS

Issue Type:	Bug
Affects Versions:	2.17.1
Assignee:	Unassigned

I have a layer with an external raster style graphic, with a size entered in the UI. The corresponding output from the GetCapabilities document is:

&lt;Style&gt;
&lt;Name&gt;ODCambodia:Phnom Penh&lt;/Name&gt;
&lt;Title&gt;A raster style&lt;/Title&gt;
&lt;LegendURL width="560" height="2104"&gt;
&lt;Format&gt;image/jpeg&lt;/Format&gt;
&lt;OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" xlink:href="/geoserver/ODCambodia/ows?service=WMS&amp;request=GetLegendGraphic&amp;format=image%2Fjpeg&amp;width=20&amp;height=20&amp;layer=Phnom_Penh_Land_Use_2035"/&gt;
&lt;/LegendURL&gt;
&lt;/Style&gt;
&lt;/Layer&gt;

Note that the LegendURL has the correct dimensions, but the provided URL requests a height/width of 20.

This causes issues with client software requesting an incorrectly formatted legend.

Potential fixes:

Remove the Height/width tags from the url
Add the correct Height/Width tags from the External Legend
