calculateWidthDependentElements function is called too often

[shadowbas]

Describe the bug calculateWidthDependantElements causes a considerable slowdown. This is mostly due to the fact that it is called in ngDoCheck.

This computation is used to determine if buttons should be visible or collapsed into a collapsable dropdown. The components that depend on this computation can be found in the following screenshots.

Solution Instead of performing this calculation on ngDoCheck (which is run on every Angular re-render) it should be done whenever a resize of relevent elements occur. The relevant element being the container element in which the buttons are situated.

Yes that does seem a little ridiculous (title updated as misspelled the function name)
