(edited after more testing) Pulling my hair out....after updating to 3.4 the edit sketch tool is no longer retained after finishing a sketch when using the Modify Features: Reshape tool. In the prior versions if editing with a sketch tool other than the default "Line" tool, the selected tool was retained after finishing a reshape sketch.
Now, after completing a sketch the tool changes to the default "Line" tool. This is terrible if you are trying to do multiple reshape edits with the same tool (very common). I figured there must be some setting where this can be changed, but I can't find it. Any ideas or alternatives to keep the active edit sketch tool in 3.4 or is this another example of long standing functionality broken with an update?
