Unexpected change of entries in bibtex file

[amanjitsk]

Here is an example of a bibtex entry that is incorrectly update when using rebiber.

@article{Lu_2023,
doi = {10.1088/1361-6544/acf988},
url = {https://dx.doi.org/10.1088/1361-6544/acf988},
year = {2023},
month = {sep},
publisher = {IOP Publishing},
volume = {36},
number = {11},
pages = {5731},
author = {Yulong Lu and Dejan Slepčev and Lihan Wang},
title = {Birth–death dynamics for sampling: global convergence, approximations and their asymptotics},
journal = {Nonlinearity},
abstract = {Motivated by the challenge of sampling Gibbs measures with nonconvex potentials, we study a continuum birth–death dynamics. We improve results in previous works (Liu et al 2023 Appl. Math. Optim. 87 48; Lu et al 2019 arXiv:1905.09863) and provide weaker hypotheses under which the probability density of the birth–death governed by Kullback–Leibler divergence or by χ 2 divergence converge exponentially fast to the Gibbs equilibrium measure, with a universal rate that is independent of the potential barrier. To build a practical numerical sampler based on the pure birth–death dynamics, we consider an interacting particle system, which is inspired by the gradient flow structure and the classical Fokker–Planck equation and relies on kernel-based approximations of the measure. Using the technique of Γ-convergence of gradient flows, we show that on the torus, smooth and bounded positive solutions of the kernelised dynamics converge on finite time intervals, to the pure birth–death dynamics as the kernel bandwidth shrinks to zero. Moreover we provide quantitative estimates on the bias of minimisers of the energy corresponding to the kernelised dynamics. Finally we prove the long-time asymptotic results on the convergence of the asymptotic states of the kernelised dynamics towards the Gibbs measure.}

I got this from https://iopscience.iop.org/article/10.1088/1361-6544/acf988. Saving it in a file and running rebiber (rebiber -i file.bib -o corrupt.bib) yields a bibtex file with the following contents (incorrectly!)

@article{Lu_2023,
 author = {Yulong Lu and Dejan Slepčev and Lihan Wang},
 journal = {ArXiv preprint},
 title = {Birth–death dynamics for sampling: global convergence, approximations and their asymptotics},
 url = {https://arxiv.org/abs/1905.09863},
 volume = {abs/1905.09863},
 year = {2019}
}

My guess is that rebiber is somehow getting thrown off by the reference to the 2019 paper in the abstract entry, but it is very unexpected that rebiber is searching through the abstract to override explicitly provided entries like journal, year etc.
