1759 * W2-B (current chain of blockerPeer, W2 is blocked by blockerPeer)

1849 * When a window is modally unblocked, it should be removed from its blocker

1852 * The problem is that we cannot simply restore window's original
1853 * TRANSIENT_FOR hint (if any) and link prevTransientFor and
1854 * nextTransientFor together as the whole chain could be created as a merge
1855 * of two other chains in addToTransientFors. In that case, if this window is
1856 * a modal dialog, it would lost all its own chain, if we simply exclude it
1857 * from the chain.
1858 * The correct behaviour of this method should be to split the chain, this
1859 * window is currently in, into two chains. First chain is this window own
1860 * chain (i. e. all the windows blocked by this one, directly or indirectly),
1861 * if any, and the rest windows from the current chain.
1862 *
1863 * Example:
1864 * Original state:
1865 * W1-B1 (window W1 is blocked by B1)
1866 * W2-B2 (window W2 is blocked by B2)
1867 * B3 is shown and blocks B1 and B2:
1868 * W1-W2-B1-B2-B3 (a single chain after B1.addToTransientFors() and B2.addToTransientFors())
1869 * If we then unblock B1, the state should be:
1870 * W1-B1 (window W1 is blocked by B1)
1871 * W2-B2-B3 (window W2 is blocked by B2 and B2 is blocked by B3)
