Maximum length of Url property

Hi,

I'm getting the following error when adding an external URL in edit mode that is longer than 255 chars:

Could not save property, and it has been reverted. Please try again.
"Src" has exceeded its limit of 255 characters.

Logfile:

EPiServer.Core.InvalidPropertyValueException: "Src" has exceeded its limit of 255 characters.

at EPiServer.Core.PropertyData.SetPropertyValue(Object value, SetPropertyValueDelegate doSet)
at EPiServer.Cms.Shell.UI.Rest.ContentChangeManager.UpdateProperties(IDictionary`2 properties, IContent content)

I wonder if it is possible to allow Url's that are longer than 255 chars?

Thanks!
