bug#25309: 11.89.8; multi-level script fontification stacks incorrectly

[Gennady Uraltsev]

Hello Everyone,

I was testing out this new mode and there seems still to be some small
problem. The simplest case is as follows:

write the following

$1=x^2$

in the standard order and make sure that electric $ mode is off i.e. the
typing should look like this (with | being the cursor):

|
$|
$1|
$1=|
$1=x|
$1=x^|
$1=x^2|
$1=x^2$|

Everything works fine. However let's try this order:

|
$|
$1|
$1=|
$1=x|
$1=x$|
$1=x|$
$1=x^|$
$1=x^2|$

Notice that $ is then "raised". Now erase the exponents by doing
$1=x^2|$
$1=x^|$
$1=x^$
The problem is that the closing $ is still raised.


When I have more info I'll write more.

Cheers,

Gennady
