1734 * chain, see {@link #addToTransientFor addToTransientFors} method for the
1735 * chain definition.
1736 * The problem is that we cannot simply restore window's original
1737 * TRANSIENT_FOR hint (if any) and link prevTransientFor and
1738 * nextTransientFor together as the whole chain could be created as a merge
1739 * of two other chains in addToTransientFors. In that case, if this window is
1740 * a modal dialog, it would lost all its own chain, if we simply exclude it
1741 * from the chain.
1742 * The correct behaviour of this method should be to split the chain, this
1743 * window is currently in, into two chains. First chain is this window own
1744 * chain (i. e. all the windows blocked by this one, directly or indirectly),
1745 * if any, and the rest windows from the current chain.
1746 *
1747 * Example:
1748 * Original state:
1749 * W1-B1 (window W1 is blocked by B1)
1750 * W2-B2 (window W2 is blocked by B2)
1751 * B3 is shown and blocks B1 and B2:
1752 * W1-W2-B1-B2-B3 (a single chain after B1.addToTransientFors() and B2.addToTransientFors())
1753 * If we then unblock B1, the state should be:
1754 * W1-B1 (window W1 is blocked by B1)
1755 * W2-B2-B3 (window W2 is blocked by B2 and B2 is blocked by B3)
1756 *
1757 * This method should be called under the AWT lock.
