Clamping behavior in the new slip operator (added in #137072) would silently fail if any strip(s) in the selection did not have enough underlying content to fill the strip bounds. This patch allows the user to continue slipping along a clamp defined by the strips that support it. A warning in the status bar is also added in this case. If no strips can clamp, the button is disabled entirely, with only the warning present. Images available in the PR. Pull Request: https://projects.blender.org/blender/blender/pulls/137980
