1754 * When a window is modally unblocked, it should be removed from its blocker
1755 * chain, see {@link #addToTransientFor addToTransientFors} method for the
1756 * chain definition.
1757 * The problem is that we cannot simply restore window's original
1758 * TRANSIENT_FOR hint (if any) and link prevTransientFor and
1759 * nextTransientFor together as the whole chain could be created as a merge
1760 * of two other chains in addToTransientFors. In that case, if this window is
1761 * a modal dialog, it would lost all its own chain, if we simply exclude it
1762 * from the chain.
1763 * The correct behaviour of this method should be to split the chain, this
1764 * window is currently in, into two chains. First chain is this window own
1765 * chain (i. e. all the windows blocked by this one, directly or indirectly),
1766 * if any, and the rest windows from the current chain.
1767 *
1768 * Example:
1769 * Original state:
1770 * W1-B1 (window W1 is blocked by B1)
1771 * W2-B2 (window W2 is blocked by B2)
1772 * B3 is shown and blocks B1 and B2:
1773 * W1-W2-B1-B2-B3 (a single chain after B1.addToTransientFors() and B2.addToTransientFors())
1774 * If we then unblock B1, the state should be:
1775 * W1-B1 (window W1 is blocked by B1)
1776 * W2-B2-B3 (window W2 is blocked by B2 and B2 is blocked by B3)
1777 *
1778 * This method should be called under the AWT lock.
