Some UI elements unresponsive to zoom feature

[m-nadji-tehrani]

There are some UI elements that are not adjusting size upon zoom in/out. Here is a list of few but do a full audit for potentially more:

• tooltips
• dropdown text (e.g. input cortical area list when adding new cortical area)

tooltips and dropdown (popupmenu) now respond to zoom
