Wt

By dragging the bottom right corner of the WTextArea a layout with JavaScript implementaion doesn't respond to it. Even if his parent widget changes size.

Here is my test code to the screenshot.

`auto layout1 = std::make_uniqueWt::WVBoxLayout();
layout1->addWidget(std::make_uniqueWt::WTextArea("Flex"));
layout1->addWidget(std::make_uniqueWt::WTextArea());
layout1->addWidget(std::make_uniqueWt::WTextArea());

auto layout2 = std::make_uniqueWt::WVBoxLayout();
layout2->setPreferredImplementation(Wt::LayoutImplementation::JavaScript);
layout2->addWidget(std::make_uniqueWt::WTextArea("JavaScript"));
layout2->addWidget(std::make_uniqueWt::WTextArea());
layout2->addWidget(std::make_uniqueWt::WTextArea());

auto mainLayout = std::make_uniqueWt::WHBoxLayout();
mainLayout->addLayout(std::move(layout1));
mainLayout->addLayout(std::move(layout2));

Wt::WDialog dialog("Layouts");
dialog.contents()->setLayout(std::move(mainLayout));
dialog.exec();`
