Equation Bug

I've encountered a bug with the display of equations when they are placed
within tables or columns. I've been able to reproduce the problem within
tables, but have not yet reproduced the bug when equations are located within
columns.

The problem is that equations and text are rendered incorrectly, usually
with equations disappearing and the text overwriting where they should be,
but the equations still exist within the file: if you get lucky, the box
which shows up when you hover over the equations will show up below text or
in empty spaces, sometimes where the equations are supposed to be, and
sometimes not.

I've been able to reproduce the bug by creating a document and entering
dummy content in order to get the equations to span a page break. Then I
create a two-column table, and in the left side proceed to enter equations,
separated by line breaks but NOT paragraph breaks (e.g. Shift-Enter rather
than Enter). The exact text and steps I took are given below, where the
margins are the standard 1" and text spacing is the default spacing.

A[Enter]
B[Enter]
C[Enter]
D[Enter]
E[Enter]
F[Enter]
G[Enter]
H[Enter]
I[Enter]
J[Enter]
K[Enter]
L[Enter]
M[Enter]
N[Enter]
O[Enter]
P[Enter]
Q[Enter]
R[Enter]
S[Enter]
T[Enter]
U[Enter]
V[Enter]
W[Enter]
[Insert 2x1 Table]
[Alt+=]f_k[Space]=\mu[Space]N[Shift+Enter]
tan(\theta)=sin(\theta)/cos(\theta)[Shift+Enter]
x=x_0+v_0[Space]t+1/2[Space]

And that is where the problem occurs. The Table jumps down to the next
page, but if you select the equations shown on the screen, the bounding boxes
show up in the places where the equations should be: 2 are still on page 1,
and one is one page 2. In this simple example, the consequences aren't bad,
but I've run into this problem catastrophically on occasion. If the same
sequence of equations is added but without the table, then the equations act
as they should.

Also, sometimes the equations show up fine as I'm creating the document, but
when I reopen a saved document, this same problem shows up. The only way to
correct it is to delete all of the equations and retype them.

I suspect the problem with the equations inside of columns has to do with
the section breaks, but I have not yet made a reproducable example. I'll add
information about the problem if I run into it again.
