Wt

With Wt 4.12.0 (vs. 4.10.0), there is a regression where a WTableView displays an unnecessary horizontal scrollbar. It seems to be triggered by the presence of a vertical scrollbar and a git bisect indicates that the issue started with commit 4.10.4-54-g43ac1cf5.

Attached is a sample app that demonstrates the issue (test_WTableView_gets_horizontal_scrollbar_20250817a.C).

Screenshots of the sample app captured with Firefox 141.0 on Linux for Wt 4.10.0 and Wt 4.12.0 are also attached.
