Anna Koskinen c8e04dc5b3 Fix to LayoutManager size calculations during transform. (#12138) * Fix to LayoutManager size calculations during transform. - ComputedStyle is slower but more reliable than using getBoundingClientRect, which does not work as expected if a transform has been applied to the element or one of its parents. This is a problem e.g. with PopupView, where getBoundingClientRect will return too small size (or even zero size) for all the popup contents while the opening animation is active. ComputedStyle ignores the transform and returns the expected value. - The presence of the element in DOM must be checked before the size is requested from ComputedStyle, if the element has disappeared from DOM without a warning and calculation is attempted anyway, the browser gets stuck. - Possibility to configure LayoutManager to use the less reliable calculations for applications where the slight performance difference is more important than layout issues within elements that have transform animations. - Manual test, problem isn't reproducible by TestBench.

Fix to LayoutManager size calculations during transform. (#12138)

* Fix to LayoutManager size calculations during transform.

- ComputedStyle is slower but more reliable than using
getBoundingClientRect, which does not work as expected if a transform
has been applied to the element or one of its parents. This is a problem
e.g. with PopupView, where getBoundingClientRect will return too small
size (or even zero size) for all the popup contents while the opening
animation is active. ComputedStyle ignores the transform and returns the
expected value.
- The presence of the element in DOM must be checked before the size is
requested from ComputedStyle, if the element has disappeared from DOM
without a warning and calculation is attempted anyway, the browser gets
stuck.
- Possibility to configure LayoutManager to use the less reliable
calculations for applications where the slight performance difference is
more important than layout issues within elements that have transform
animations.
- Manual test, problem isn't reproducible by TestBench.
