The description of a KernelSmoothing fitted distribution can be lost sometimes

[mbaudin47]

What happened?

In the script below, I create a distribution, configure its description and generate a sample from it. Then I create a kernel smoothing estimator of the distribution. The description of the fitted distribution is "v0" instead of "A", as expected. If I comment out the configuration of the bounding option, then the correct description is obtained.

How to reproduce the issue?

The script:

import openturns as ot
x = ot.Uniform()
x.setDescription(["A"])
data = x.getSample(100)
kde = ot.KernelSmoothing()
kde.setBoundingOption(ot.KernelSmoothing.LOWER)  # Comment this line: succeeds!
kdeDistribution = kde.build(data)
kdeDistribution.getDescription()  # Expected: "A"

produces:

[v0]
