/* a word of explanation about the flex-shrink values employed here:
there are 3 priotized categories of screen real-estate grabbing,
each with a flex-shrink difference of 4 order of magnitude,
so they ideally wouldn't affect each other.
lowest category: .mx_RoomSubList
2018-12-18 16:32:46 +03:00
flex-shrink: 10000000
distribute size of items within the same categery by their size
middle category: .mx_RoomSubList.resized-sized
2018-12-18 16:32:46 +03:00
flex-shrink: 1000
applied when using the resizer, will have a max-height set to it,
to limit the size
highest category: .mx_RoomSubList.resized-all
2018-12-18 16:32:46 +03:00
flex-shrink: 1
small flex-shrink value (1), is only added if you can drag the resizer so far
so in practice you can only assign this category if there is enough space.
