These simple styles just stopped working out of the blue. They worked fine until today.
<Style x:Key="textColumnElementStyle" TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type TextBlock}}"><Setter Property="Padding" Value="5,1" /></Style><Style x:Key="textColumnEditingElementStyle" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"><Setter Property="Padding" Value="2,0" /></Style>
These both shows errors on the `BasedOn` property. The resource "{x:Type TextBlock}" could not be resolved.
The resource "{x:Type TextBox}" could not be resolved.
If I copy and pase one of the styles right next to itself, there is no error on the pasted style.
<Style x:Key="noErrorOnThisStyle" TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type TextBlock}}"><Setter Property="Padding" Value="5,1" /></Style><Style x:Key="textColumnElementStyle" TargetType="{x:Type TextBlock}" BasedOn="{StaticResource {x:Type TextBlock}}"><Setter Property="Padding" Value="5,1" /></Style><Style x:Key="textColumnEditingElementStyle" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"><Setter Property="Padding" Value="2,0" /></Style>
