ConstraintLayout Regression

This repository contains a bare-bones Android application which contains a super simple layout file that demonstrates a change in behaviour from version 2.0.0-beta4 of the ConstraintLayout library to versions 2.0.0-beta5 and 2.0.0-beta6. The change in behaviour appears to me to be a bug and not an intended change.

The layout file defines three views positioned left to right, as follows:

1. A TextView with width 0dp which will expand to fill the remaining space after the other views are laid out.
2. A TextView with width wrap_content which will tightly wrap its content.
3. An ImageView with fixed width.

With version 2.0.0-beta4 of the ConstraintLayout library, the layout is rendered as follows:

However, with versions 2.0.0-beta5 and 2.0.0-beta6 of the ConstraintLayout library, the layout is rendered as follows:

Edit: See here for the bug report in IssueTracker and the suggested workaround.
