Wt

Hello, looks like this must be a bug.

• We have a program that we upgrades from Wt 3 to Wt 4.
• This program had, and still has, some rendering problems, but basically was usable.
• My idea was that new version 4.11.2 will fix my rendering problems, so I have tried to update
• I have found that my container widget that I used to edit data, now fails to render, when I reload the page, there are some traces visible as one line instead of form.
• I have other forms in this project and they all work fine, the difference is that this one has WSlider objects in it.
• This same code works well with 4.10.4 My compiler is MSVS2022 and I use cmake to generate my visual studio project, so I can easily swap wt versions.
