Problems with Room list rendering

[tyreseluo]

Issue From: #123

@joulei It seems that the room_list rendering problem we discussed last time still exists?Can you take a look and help me describe the problem?
@kevinaboos Already using your latest commit, I have push the draft code to PR #232.

this is a makepad bug that was introduced a couple of weeks ago and recently reverted. I have now updated our dependency on makepad to depend on a version that shouldn't have this problem.

I'm no longer able to replicate it as of #236 being merged in, but please test it yourself and let me know.

Ok,I will do that.
