When opening the expression assistant from a “go to another view” type Action, the cursor is placed in the search box for expressions, instead of the expression box. Actually it appears to briefly go to the expression box, then jump to the search box. This does not happen with other Action types/expression-assistants. First noticed it within last couple weeks, but just figured out exactly what was happening.
This is still happening.
Discussed this in the support ticket, but will repeat here in case others were affected – this issue should be fixed now. See release notes under Bug Fixes:
