clef change before bar line causes bar misalignment (grand staff using `%%score {R|L}`)

[AGBrown]

Environment:

• abcjs 6.4.1
• tested on and occurs in both chrome (127.0.6533.120 (Official Build) (64-bit) (cohort: Stable) ) and firefox (Version 129.0.1, Build ID 20240812083845)

Issue:

If you change the clef on a grand staff, just before the bar line, it causes the bars to be misaligned, this is on a grand staff by using %%score {R|L}

(expand for test abc).

%abc-2.1

X:0
T:Clef change test
%%barnumbers 1
%%measurenb 0
%%score {R|L}
%%stretchlast 1
Q:"Misterioso" 1/4=80
M:2/4
L:1/4
V:R clef=treble
V:L clef=bass

[V:L] C2 | C2 | C2 | C2 |]

Expected output

The bar lines should be aligned immediately after the clef change. See the following example render.

Additional notes

• Although the bar lines are misaligned, the first notes of the following bar are aligned.
• Using y space on the top stave above the clef change doesn't help
• This also displays the #1041 issue.
